Laylat-ul-Qadr (The Night of Majesty and Destiny) and simple astronomy – some reflections

May 22, 2020

Laylat-ul-Qadr (The Night of Glory and Destiny)

& simple astronomy – some reflections

Bismillah.

Laylat-ul-Qadr (LQ – The Night of Glory, Majesty, Decree and Destiny, etc.) is in one sense the climax of the month of Ramadan / Ramzan (R).

* Some of the hadiths about its exact date, even the allegedly authentic ones, are mutually contradictory, which is why scholars try to reconcile them.

* It is night-time for half the earth at any moment; the other half is in daytime. Day and night are relative to each person’s location on earth.

* It is presumably possible for the Angels & the Spirit to descend around the half of the earth that’s in night-time for a period of exactly 24 hours, thus giving a specific date for LQ. Presumably, this would start at sunset for the first location on earth from where the new crescent moon was visible.

* Since Muslims have differed for decades about the beginning of R, and hence about its odd nights, this presents a difficulty in finding LQ in the last 5 odd nights. One solution is to look for it throughout the last 10 nights. But what if LQ falls just before your last 10 nights or just after, i.e. on your Eid night whilst others are still observing R?

* Do the Angels & the Spirit descend throughout the last 10 nights?

* MY SOLUTION: Due to considerations like these, I follow the view of the Companion, Abdullah bin Mas’ood: LQ can be on any night of the year. Or we could say: it is on every night of the year. Every night is LQ!

* This is why the hadiths say: SEEK IT in the last 10 nights of R, etc., because it would be too difficult to seek it all year long. We are prepared with fasting & worship for a whole month to help find LQ during the last 10 nights, preferably in i’tikaf (spiritual retreat). Remember, the Prophet pbuh once did i’tikaf for the whole month of R in order to find LQ.

* These are some of the many wisdoms behind the spiritual practice of Ramadan/Ramzan. May ours have been blessed, and may we have found our Night of Powerful, Glorious Destiny, had all our prayers answered and been illuminated by The Light for at least another year!

PS “Better than a thousand months” means “Better than all of time.”

(khayrun min al-dahri kullihi – Tafsir Qurtubi)

In other words, Laylat-ul-Qadr is an opportunity to transcend Time, or experience Eternity or Timelessness.

I alluded to some of these lessons about Ramadan (Ramzan) & LQ in this poem, based on the famous opening of William Blake’s Auguries of Innocence:

To break your fast with a wholesome date
And recite noble verses of Light.
To seek Infinity in your unfolding Fate
And Eternity in One Night.

ليلة القدر و علم الفلك:

الليل والنهار أمران نسبيان لمكان كل شخص في الأرض، وهما آيتان من آيات الله تعالى.

والأحاديث في تحديد تاريخ ليلة القدر متناقضة، حتى الصحيحة منها، ولذالك حاول علماء الحديث الجمع بينها دائماً.

فنصف الأرض في أي وقت في ظلمة اليل، والنصف الآخر في ضوء النهار.

قد تنزّل الملائكة والروح لمدة ٢٤ ساعة كل عام، فتكون لليلة القدر تاريخ معيّن. ولكن عندنا مشكلة: الاختلاف في بداية شهر رمضان يؤدي الى اختلاف في اليالي العشرة الأخيرة.

من أجل هذه الاعتبارات وغيرها، أرى برأي عبد الله بن مسعود رضي الله عنه أن ليلة القدر قد تقع في أي ليلة في السنة. ولذالك جاء في الأحاديث «إلتمسوا ليلة القدر في العشرة الأخيرة من شهر رمضان» لأن إلتماسها طول العام أمر محرج وصعب جداً على المسلمين.

فشرع شهر العبادة من صوم وصلاة وزكاة وإطعام المساكين وإعتكاف وغيرها من أعمال الخير ليسهل إلتماس الليلة العظمى في العام:

إنا أنزلناه في ليلة القدر، وما أدرىٰك ما ليلة القدر؟ ليلة القدر خير من ألف شهر، تنزّل الملائكة والروح فيها بإذن ربهم من كل أمر، سلام هي حتى مطلع الفجر.

ومعنى «خير من ألف شهر» يعنى: «خير من الدهر كله» كما ذكره الإمام القرطبي في تفسيره. فإن وجدت ليلة القدر، فكأنما خرجت من حدود الزمان ولمست قدسية الدهر وذقت معنى الخلود في جنات النعيم.

اللهم بارك لنا في شهرنا و أيامنا وليالينا، آمين.

APPENDIX: A GLIMPSE OF SOME OF THE VIEWS ABOUT THE DATE OF LQ, TO SHOW THE IMMENSE DIVERSITY ABOUT THIS IN THE ISLAMIC TRADITION

NB: where “[odd nights of the] last 10” is mentioned, even this was disagreed about, e.g.: Ibn Hazm stated that if the month has 30 days, then these odd nights are 21, 23, 25, 27 & 29 but if the month has 29 days, then the last 10 nights are nights 20-29 and hence the odd nights are 20, 22, 24, 26 & 28! This was another argument for seeking LQ in all of the last 10 nights, because in the past, we were unable to know for sure in advance how many days the month would have.

IBN KATHIR

Hadith (Tayalisi): 27 or 29

Hadith (Ahmad): LQ in last 10, odd nights: 29 or 27 or 25 or 23 or the last night of the month.  The hadith has other details.  IK: the isnad is hasan, but the matn has strange, weak content (gharabah) and in some versions, rejected (nakarah) content or meaning.

Hadith (Ibn Abi Asim): LQ in last 10.

Hadith (Ahmad): Seek it in the first 10 or last 10 … Seek it in the last 10 … Seek it in the last 7.

Narration: from Ibn Mas’ood and those who followed him of the people of knowledge of Kufa that it is found throughout the year, and is hoped for in every month equally. (IK disagrees with this view)  Ibn Mas’ood used to say, “If you stand in prayer at night all year long, you will find LQ.”

Hadith (Abu Dawud): LQ may be throughout R.

Narration: from Abu Hanifa: LQ is hoped for throughout R.  This is also a view quoted by Ghazzali [i.e. in the Shafi’i madhhab? – UH] Rafi’i declared this to be an extremely strange view.

LQ is the 1st night of R: Abu Razin.

LQ is 17th R, because it was the night before the Battle of Badr, described as being on the “Day of Decision” (Yawm al-Furqan) in the Qur’an, hence it relates to LQ as the night of decision, decree and destiny: narrated from the Prophet, Ibn Mas’ood, Zayd bin Arqam, ‘Uthman bin Abil-‘Aas, Imam Shafi’i & Hasan Basri.

LQ is 19th R: narrated from ‘Ali & Ibn Mas’ood.

LQ is 21st R: Hadith of Abu Sa’id al-Khudri in Bukhari & Muslim.  Imam Shafi’i said that this was the most authentic narration on the subject.

LQ is 23rd R: Hadith of Abdullah bin Anees in Sahih Muslim – it is a very similar narration to the previous hadith (21 R).

LQ is 24th R: Hadith of Abu Sa’id al-Khudri in Tayalisi. IK: the narrators are trustworthy.  Also narrated as a hadith by Bilal, but a weak isnad. Also contradicted by the next consideration:

LQ is in the first 7 of the last 10 nights: more authentic view of Bilal rA, narrated by Bukhari.  Also narrated as the view of Ibn Mas’ood, Ibn Abbas, Jabir, Hasan, Qatadah & Ibn Wahb, and from the Prophet by Wathilah bin al-Asqa’.

LQ is 25th R: based on the hadith of Bukhari from Ibn Abbas from the Prophet: Seek it in the last 10 nights: in the 9 remaining, 7 remaining, 5 remaining.

IK: Most people of knowledge understood this to mean the odd nights, but others understood it to mean the even nights, e.g. Abu Sa’id (Sahih Muslim). IK: Allah knows best.

LQ is 27th R: narrated from the Prophet, several Companions, a group of the Salaf, the preferred view in the madhhab of Imam Ahmad and quoted also from Imam Abu Hanifa.

LQ is the 7th of last 10 (i.e. 27) or with 7 remaining (i.e. 22 or 23): narrated from Ibn Abbas.

LQ is 21, 23, 25, 27, 29 or last night of the month: Hadith of Imam Ahmad.

LQ is 27 or 29: Hadith of Imam Ahmad.

LQ is the last night of R: Hadith of Ahmad, Tirmidhi, Nasa’i.

KEY:

18° refers to astronomical twilight, which begins or ends when the sun is 18 degrees below the horizon

15° refers to when the sun is 15 degrees below the horizon

12° refers to nautical twilight, which begins or ends when the sun is 12 degrees below the horizon

The astronomical definition of “dawn” is disputed, with various Muslim religious authorities adopting one of the three possible definitions given above.

*** in the above table means that the timing is not available, because the sun does not reach that far below the horizon. This happens every year during the summer at high latitudes, such as the UK.

 

NOTES:

  1. We must emphasise that the actual dates of the beginning of Ramadan and Eid, given above, are subject to vary by one or two days, within Muslim communities in the UK, due to different community approaches to determining these dates.
  2. If we use 18° astronomical twilight (Sun’s depression = 18 degrees) as the start of dawn, the fasting start time and fasting length are undefined for most of Ramadan 2020 in Edinburgh & Belfast. They are defined for most of the month, except towards its end, in Cardiff & London, where the fasting length is around 17-18 hours.
  3. If we use 15° (Sun’s depression = 15 degrees) as the start of dawn, the fasting start time and fasting length are undefined for most of Ramadan 2020 in Edinburgh & Belfast, except towards its end, where the fasting length is 17-19 hours. However, dawn does occur throughout the month in both London and Cardiff, giving fasting lengths of 16.5-18.5 hours.
  4. If we use 12° nautical twilight (Sun’s depression = 12 degrees) as the start of dawn, this results in fasting hours during Ramadan 2020 in London and Cardiff of 16-18 hours, in Belfast of 16.5-18.5 hours, and in Edinburgh of 16.5-19 hours.
  5. If we use Sunrise as the start of fasting, this results in fasting hours during Ramadan 2020 in London and Cardiff of 14.5-16 hours, in Belfast of 15-16.5 hours, and in Edinburgh of 15-17 hours.

UK Ramadan fasting times for 2017

May 22, 2017

Bismillah. As I’ve written about before, there are different views on excessive fasting hours in the summer at high latitudes such as the UK. I am not going to repeat those, but try to provide the scientific, astronomical data, information and knowledge to help support others to come to their own conclusions.

In this post, I give the dawn, sunset & possible fasting times for 2017, when mid-summer occurs towards the end of Ramadan: the average fasting times are slightly shorter than last year (2016), when they were maximum in the 33-year lunar/solar cycle, but not by much.

*I urge mosque timekeepers (muwaqqits) or others who develop fasting timetables to be transparent about the method they are using, and not vague references like “fiqh according to Madhhab X” because there are many views in every Madhhab. E.g. using an 18-degree or even 15-degree rule gives no timings for most of the UK. Fasting timetables in the UK summer should clearly state what method is used to arrive at the beginning time of fasting. Many timetables have excessive gaps between ‘dawn’ and sunrise of 2-3 hours with no sensible justification, since this is merely one possibility amongst many others and is indeed the most difficult for people. Indeed, with the summer midnight being at 1am BST, some of these timetables are forcing people to fast from soon after midnight. With the sunset-sunrise night length being 6-8 hours across the UK, the most reasonable view within this paradigm in my view is that of the last 1/6th, 1/7th or 1/8th of the night, giving a fasting time beginning an hour before dawn. However, other approaches are even more preferable. Over to others for discussion and to arrive at their own conclusions.*

Examples of dawn/sunset timings for the UK, 2017 (four UK capital cities)

This data is taken from HMNAO’s Websurf 2.0 website, and was reproduced with permission by the ASCL in their Ramadan 2017 guidelines. I have used the four UK capital cities, with three dates for each, roughly corresponding to the beginning, middle & end of Ramadan.

15D refers to when the sun is 15 degrees below the horizon

NAUT refers to nautical twilight, when begins or ends when the sun is 12 degrees below the horizon

The astronomical definition of “dawn” is disputed, with various Muslim religious authorities adopting one of the three possible definitions given above.

*** in the above table means that the timing is not available, because the sun does not reach that far below the horizon. This happens every year during the summer at high latitudes, such as the UK.

 

NOTES:

  1. As confirmed by HMNAO, there is always a possible error of 1-2 minutes in sunrise and sunset timings: although we can calculate exactly the position of the sun relative to our horizons, refraction of the sun’s rays can introduce an error: the sun may be below the horizon but we see it just above, due to refraction.  (This does not always happen, of course: hence the error will be zero, one or two minutes.) This means that technically, mosque prayer timetables may wish to add 2 minutes to sunset timings and subtract 2 minutes from sunrise timings, just to be safe about the timings of the sunset and dawn prayers, and for breaking the fast.  However, this might also be hair-splitting: I recommend making these adjustments, but would not worry if they are not made.
  2. If we use astronomical twilight (Sun’s depression = 18 degrees) as the start of dawn, this does not occur at all during Ramadan 2017 in any of the four capital cities. Therefore, the fasting start time and fasting length would be undefined.
  3. If we use (Sun’s depression = 15 degrees) as the start of dawn, this does not occur at all during Ramadan 2017 in Edinburgh or Belfast. Therefore, the fasting start time and fasting length would be undefined in those cities. However, it does occur in London and Cardiff, giving fasting lengths of 19.5-20 hours during the month.
  4. If we use nautical twilight (Sun’s depression = 12 degrees) as the start of dawn, this results in fasting hours during Ramadan 2017 in London and Cardiff of 18-19 hours, and in Belfast of 19-20.5 hours. We only get defined fasting hours at the beginning of Ramadan for Edinburgh, of 19.5-20 hours.
  5. Hence, it should be obvious that some ijtihad is required, eg a fraction of the night or a lower angle of the Sun below the horizon to designate the “beginning” of dawn. Another option is sunrise-sunset fasting rather than dawn-sunset, as done by some of the Sahaba (Tafsir Ibn Kathir & Ibn Hazm’s Al-Muhalla), or other, non-literalist options that I have described elsewhere.

NB: Our local latitude determines the lowest angle the Sun will dip below the horizon at mid-summer (~22 June). This angle can easily be calculated by subtracting 66.5 degrees (the latitude of the Arctic & Antarctic Circles) from the local latitude.

E.g.:

Within the Arctic Circle (66.5 deg or higher latitude), lowest Sun angle = zero or higher: the sun doesn’t set at all in the “land of the midnight sun.”

Edinburgh (56.0 deg lat): lowest Sun angle at midsummer = 56.0 – 66.5 = 10.5 deg below the horizon

Belfast (54.6 deg lat): lowest Sun angle at midsummer = 54.6 – 66.5 = 11.9 deg below the horizon

London & Cardiff (both 51.5 deg lat): lowest Sun angle at midsummer = 51.5 – 66.5 = 15 deg below the horizon

*NB: even using these angles of 10.5 deg, ~12 deg, 15 deg & 15 deg for Edinburgh, Belfast, London & Cardiff respectively will give very long fasting hours, as the table of timings above demonstrates.

Btw for Paris (48.9 deg lat): lowest Sun angle at midsummer = 48.9 – 66.5 = 17.6 deg below the horizon, so using the 18-degree rule gives no timings for Paris or anywhere north of it either at midsummer.

Have a blessed Ramadan 1438 / 2017!

UK Ramadan fasting times for last year (2016)

I am not going to repeat those, but try to provide the scientific, astronomical data, information and knowledge to help support others to come to their own conclusions.

In the first of these posts, I am including the dawn, sunset & possible fasting times from last year (2016) because then, mid-Ramadan coincided with mid-summer, hence giving the longest average fasting lengths in the 33-year cycle as the lunar years move through solar years.

Islam and Science workshop presentations – London 2013

July 27, 2015

Bismillah. I have been working on the report for the “Islam & Science – The Big Questions” (of science and Islamic theology) Task Force that I convened in Istanbul in February 2015, chaired by Prof. Ekmeleddin Ihsanoglu, by the grace of God.  The Task Force report will be published in a few weeks, God-willing.

This reminded me that we had not sufficiently circulated the presentations from our “Islam & Science” workshop in London from 2013, some of which the current Task Force builds on.  So, here are the presentations from that workshop, as well as the final report. These should be of interest to anyone interested in cutting-edge discussions about Islam and science, religion and science, etc. University students should find these presentations a useful resource, especially for their own dissertations and theses. Enjoy!

Islam and Science Workshop – London 2013 – A Summary

February 22, 2013

Bismillah.  This is a cross-post from http://www.quilliamfoundation.org/events/islam-science-workshop-2013/

Quilliam, in association with the Université Interdisciplinaire de Paris, the American University of Sharjah and Muslim-Science.com, organised and hosted an international workshop entitled “Islam and Science: A Reasoned Approach” for students and young researchers, 18th-20th January 2013 at the Institute of Education, University of London, UK.

The participants consisted of 23 people selected by submission of essays on Science-Religion topics and/or their suitability as “disseminators of ideas” following on from the workshop. These 23 participants included three people from France, the USA and Egypt. There were a total of seven speakers at the workshop: three from the UK, two from France and one each from the UAE and Pakistan.

Introduction – Friday 18th January 2013

The workshop began with a screening of the 1-hour documentary film, Science and Islam – Dialogues for the 21st Century, which was produced by the Université Interdisciplinaire de Paris and featuring interviews with 22 leading scientists, theologians, philosophers and thinkers about the interfaces between religion and science in general, and focusing on Islam in particular.

This was followed by a presentation by Ehsan Masood, author of the BBC series-accompanying book, Islam and Science: A History, a presentation entitled Ibn Sina (Avicenna) – The Man Who Knew Everything, about the life, work and influence throughout Islamic and Christian history of this early Muslim polymath. A lively discussion followed about Ibn Sina’s philosophy and methodology and the scientific rationalisation of miracles.

Saturday 19th January 2013

Prof. Jean Staune (Université Interdisciplinaire de Paris) started with presentation on Science and Religion in the World today & New Paradigms of Science, in which he summarised the major developments in 20th-century science such as relativity and quantum theories in physics, Godel’s theorem in mathematical epistemology, and De Duve and Conway-Morris’ ideas of direction, non-randomness, and convergence in biological evolution. He showed how these “new paradigms” have influenced the discourse in “Science and Religion”, and how this field has become a growing academic discipline in its own right with chairs at Oxford, Cambridge and Harvard. This was followed by Prof. Nidhal Guessoum (American University of Sharjah), who gave a general overview of the main topic, Islam and Science, showing why “modern science” (particularly “methodological naturalism”) poses a challenge for traditional religious views and discussing the various contemporary Muslim responses to the challenge, ranging from Nasr’s “Sacred Science” and Sardar’s “Islamic/Ethical Science” to Salam’s “Universal Science”, ending with his own “Averroesian Harmonization.”

Yasmin Khan (former curator at both the Science Museum and the British Library) spoke on The 1001 Inventions Exhibition at the Science Museum, London: Engaging the Public in a Multicultural History of Science, a behind-the-scenes look at the challenges of commissioning the most successful touring exhibition in the history of the Science Museum, with a screening of the exhibition’s central 15-minute film, 1001 Inventions and The Library of Secrets, starring Sir Ben Kingsley as Al-Jazari.

Dr. Athar Osama (of Muslim-Science.com) complemented the day’s philosophical, theological, historical, civilisational and public-outreach themes with a sobering presentation on Science Policy in the Muslim World Today: Challenges and Prospects, focusing on governmental public policy and investment in science education and research and an analysis of the funding and work of COMSTECH, the OIC’s arm for science and technology.

Sunday 20th January 2013

Dr. Jean Staune gave a fascinating presentation on the Theories of Evolution. The philosopher of science showed multiple lines of evidence that evolution is an indisputable fact, but one that should not be confused with Darwinism. Based on the research of leading palaeontologists such as Conway-Morris and on the work of Nobel laureate De Duve and others, Staune insisted that the current Darwinian theory of evolution is incompatible at best, and presented ideas implying that evolution is a process leading, sooner or later, to beings like us with a consciousness of their own existence and the ability to seek God.

This was followed by a joint presentation on Islam and the Theory/Fact of Evolution by Prof. Nidhal Guessoum and Dr. Usama Hasan (Quilliam). The presentations included theological and scriptural arguments supporting evolution as well as a history of evolutionary ideas within Muslim civilisation since the 9th century CE from Al-Jahiz and the Brethren of Purity through to Rumi and Ibn Khaldun, a history recognised by a number of historians, Muslim and non-Muslim ones. Also covered was the acceptance of biological evolution by 19th/20th-century Muslim theologians such as Husain al-Jisr (nicknamed “the Ash’ari of our times” by Afghani), and ‘Abd al-Sabur Shahin, a well-known scholar of Al-Azhar. Current Muslim resistance to scientific facts was illustrated with historical precedents of misreading the Qur’an to make inflexible but erroneous assertions about scientific matters, such as Ibn Kathir and Shanqiti’s insistence that the earth was created before the heavens, Suyuti’s insistence that the earth is flat and Ibn Taymiyyah’s assertion that cattle (sheep, goats, cows and camels) were created in heaven (which would imply that modern-day followers of Ibn Taymiyyah who insist that humans were created in heaven and descended from there must also believe the same about those four species of mammals).

The sessions by Staune, Guessoum and Hasan illustrated well the irony that whilst modern biology, built on evolution, has succeeded in mapping the entire human genome as well as the DNA of thousands of other species, and new fields emerge such as astrobiology and the origin-of-life research looking at deep-sea volcanoes, many Muslims (and Christians) continue to debate whether or not evolution (including that of humans) is a fact, despite the overwhelming scientific evidence.

Dr. Bruno Abdelhaq Guiderdoni (Director of the Lyon Observatory) gave a fascinating presentation on Islam & Cosmology: Yesterday and Today, based on the mind-boggling discoveries of modern astronomy, including the existence of exo-planets in earth-like habitable orbits around stars other than the sun. In his lecture, Dr. Guiderdoni stressed the need to read the “Book of Nature” along with the “Book of God” and to maintain the inseparability of science and ethics. The discussion included topics such as the possibility of a multiverse and the question of extra-terrestrial intelligence and life-forms.

Dr. Guiderdoni’s emphasis on ethics led nicely to the session by Dr. Usama Hasan on Islam, Science and Ethics, in which he presented the theory of Maqasid al-Sharia (The Universal, Higher Objectives of Islamic Law) as an Islamic framework for ethics suitable for “Universal Science.” The framework is based on the Islamic principles of justice as minimum, compassion as maximum, promoting benefit and avoiding harm. The theory was illustrated with reference to ethical questions around family planning, abortion and organ transplants.

The workshop concluded with an open and long discussion session involving all participants, further exploring the ideas presented at the workshop and possible next steps to take the exciting conversations forward.

When is Eid al-Fitr? 1433 / 2012

August 15, 2012

Bismillah.  *Sunday 19th August 2012 is a sensible date for Eid al-Fitr 1433 for the whole world.*

Please refer to the Moonwatch data (http://astro.ukho.gov.uk/moonwatch/nextnewmoon.html), that shows:

Friday 17/8: Conjunction and astronomical new moon around 15.54 UT (GMT) – no crescent moon is visible anywhere on earth that night, except possibly in the Southern Pacific, very close to the solar date-line.

Saturday 18/8: The crescent moon is visible throughout the Southern Hemisphere, plus a few places north of the Equator, but not in Asia, the Middle East, North Africa or Europe.

Sunday 19/8: The crescent moon is easily visible throughout the whole world, including the UK.

Hence:

Sunday 19th August 2012 is a sensible date for Eid al-Fitr 1433 for the whole world: there is expected to be a high degree of agreement on this, as has happened in previous years.  (Those who began Ramadan on Fri/Sat 20/21 July will complete 30/29 days of fasting and celebrate Eid together.)

For those following local sightings, Monday 20th August 2012 would be Eid al-Fitr 1433 in the UK.

May Allah bless us all during the remainder of Ramadan and on the glorious day of Eid al-Fitr (the Festival of Breaking the Fast).

Senior Researcher in Islamic Studies at Quilliam & Fellow of the Royal Astronomical Society

15th August 2012 / 26th Ramadan 1433

About the Ramadan start date this year 1433/2012

August 15, 2012

Bismillah.  This is what happened:

Saudi claimed to have seen the moon on Thursday 19/7 and began Ramadan on Friday 20/7; many other countries followed suit.  However, we know definitely that such a sighting was impossible, for at least two reasons:

(i) from precise astronomical calculations (www.crescentmoonwatch.org )

(ii) had it been genuine, there would have been an easier sighting from the Southern US and Central America on the same date, which there wasn’t.  Refer to Ibn Taymiyyah’s fatwa on moonsighting (elsewhere on this blog), as well as Sheikh Afif al-Akiti’s detailed treatise on the subject.

However, the ECFR (www.e-cfr.org ) had already announced that Ramadan would begin on Friday 20/7, due to the expected visibility of the crescent moon from South America on 19/7.  The ECFR mentioned Santiago (Chile) in its declaration.  Note that the ECFR’s declaration implied that they agreed that moonsighting was impossible in Saudi on that date, but ruled that the Chile sighting was enough for the whole world, even if it occurred many hours after local sunset elsewhere: e.g. the ECFR method required Australia to begin Ramadan on 20/7, even though they are about 12 hours ahead of Chile. 

Note also that this ECFR method is consistent, and is a possible approach to determining Arabian/Islamic lunar dates worldwide, using the solar date-line as an effective lunar date-line.  If people agree to use this method, it is a possible solution to the moonsighting problem, although we will need to check that it gives a reasonable pattern of 29/30-day months.

Amongst Sunni Muslims, there were three start dates:

(i) Friday 20/7 – those following the impossible Saudi sighting or the plausible ECFR method

(ii) Saturday 21/7 – those following the easier sightings around most of the world on the next day

(iii) Sunday 22/7 – for northern latitudes such as the UK, those following a local sighting.

Amongst Shia Muslims, the same three start dates were observed, based on people following the fatwa of their authority (marja’), whether Fadlallah, Khoei or Sistani respectively.
