Introduction
To establish the Hijri calendar with verified moon sightings by the human eye (Muhaqaq Ruyat Basari) is a communal obligation (Fard Al-Kifaya). The role of the public is to sight the moon and report it. The role of the Hilal Committee is to take the witness testimonies (Shahada) and declare the start of the lunar months (for Ibadah). Anyone who has sent a Hilal Report to the ICOUK website (Send Observation Report) may be invited to give a testimony to ICOUK Ulama according to this policy, which may be shared confidentially (see below) with other UK Hilal Committees/Organisations (to avoid inconveniencing the witnesses with multiple testimonies).
Importance of Testimony
It is a communal obligation (Fard Al-Kifaya) for people to give testimonies to a Hilal Committee, to fulfil the responsibilities of a group of Muslims who have sighted the crescent moon (Hilal). However, if only one or two people have sighted the moon (e.g., due to cloudy weather) then it is an individual obligation (Fard Al-Ayn) to give their testimonies to a Hilal Committee.
Allah says: "And do not conceal testimony, for whoever conceals it, his heart is indeed sinful, and Allah is knowing of what you do." (Quran 2:283). He also says: "And who is more unjust than one who conceals a testimony he has from Allah? And Allah is not unaware of what you do." (Quran 2:140)
Zaid bin Khalid Al-Juhani (ra) narrated that the Messenger of Allah(ﷺ) said: "The best of witnesses is the one who gives his testimony before being asked for it." [Tirmidhi:2297]
Witness Criteria
The vast majority of the ICOUK members follow the Quran and Sunnah according to the understanding of the Hanafi Madhab (school of thought), which has the most stringent witness criteria. Accordingly, the witness must be (a) Muslim, (b) adult, (c) sane (sound mind), (d) has good eyesight, (e) reliable/good character etc.
Number of Witnesses
A minimum of two males or two females and a male witness will be required*, although a greater number is most welcomed. If a female is unable to provide a testimony directly to the ICOUK Ulama, then she can still provide it through a male guardian (Mahram), known as Testimony-upon-Testimony (Shahada-Ala-Shahada)!
[*Note: In the case of cloudy weather at the start of Ramadan, the witness of one trustworthy male or female is accepted. A large group sighting (Jame Ghafeer) will be necessary for clear skies.]
Remote Testimony
To help the UK Ulama/Hilal Committees make rapid and accurate Hilal decisions, we will adopt a remote testimony procedure via an audio/video conference call (e.g. Skype/Zoom). Remote testimonies will be taken individually from those who have sent (positive) ICOUK Hilal Reports and whose full identity (ID) is known to the Admins. Therefore, it is important to keep your ICOUK database profile up to date with your contact details and a recent ID Photo (of head and shoulders).
Identity Verification
An ID Photo is very helpful to establish the identity of witnesses with minimum delays. A remote testimony from a stranger (unknown person) is not acceptable. The identity of males and females will be verified separately by male and female Admins and Scholars, respectively. Once the identity has been established, a voice-only testimony (i.e. with the video off) may be acceptable, InshaAllah.
Testimony Template
All witnesses will be required to use the template below, by adding the details inside the angle brackets (< >).
My name is <full name> and I am from <city/town>. I testify that I saw the moon on <date/time> <before/after> sunset. The sky was <clear/cloudy> and the moon was seen on the <left/right> of sunset by <naked eye/binoculars>. The time of sunset was <hh:mm GMT/BST>.
The witnesses may be asked to provide some additional information (e.g. direction of the crescent moon horns), but the template details are the minimum required for Shariah and Scientific purposes.
Giving False Testimony
To give false testimony is a major sin (next to Shirk) because it is one of the characteristics of a hypocrite (Bukhari:2749), and hence a person should only testify to what they are sure of (i.e., without any doubts) and not lie. Allah says: "curse of Allah upon the liars". (Quran 3:61)
Narrated Abu Bakra (ra): The Prophet (ﷺ) considered Shahadah az-Zur (giving false testimony) among the most serious of major sins. [al-Bukhari and Muslim reported it in a long Hadith]. [Bulugh:1419]
Announcement
Once the testimonies have been accepted by the ICOUK Ulama/UK Hilal Committees, the decision to start the month will be announced on the ICOUK website and/or social media channels. Other organisations may do the same via their own websites/social media channels. Note that the announcements for negative sighting reports are always later (than positive sighting reports), to allow extra time for receiving all the observation results from the last sighting point/moonset time!
Confidentiality/Privacy Policy
Any testimonies provided to the ICOUK Ulama above may be shared confidentially with other UK Hilal Committees under a Non-Disclosure Agreement (NDA). All other personal details of the witnesses will be kept strictly confidential, as per ICOUK Privacy Policy and will not be disclosed to any third parties without the prior consent of the testimony provider.

Related: Importance of Moon Sighting | Why look for the moon after the 29th date? [download pdf]
When Muslims go out for crescent moon (Hilal) observation, there are two possible outcomes:
- They actually see the moon and report the result as a positive sighting.
- They don't see the moon and report the result as a negative sighting.
It is Sunnah to look for the Hilal on the 29th lunar date and if there is a positive sighting then the new month begins from the next day.
However, if there are negative sightings then the new month begins from the day after the next day i.e. after completing 30 days.
Therefore, it is essential to report both positive and negative sightings to begin the new month with certainty and not in doubt.
Furthermore, negative sighting reports provide justification for completion of 30 days, hence it's important to report negative sightings (from all locations) just as positive sightings.
What if people don't report negative sightings?
The purpose of reporting Hilal sightings is to help the community (or nominated Hilal Committee) to make rapid and accurate decisions to begin the new month.
When they see the positive sighting reports on the 29th day, they can decide to begin the new month from the next day with certainty.
Similarly, when they see the negative sighting reports, they can decide to complete 30 days of the month with certainty.
Some people only report positive sightings and not negative sightings. This is not helpful, because when the community (or the nominated Hilal Committee) don't see the negative sighting reports, they may fall in doubt and have to wait unnecessarily long to make a decision.
Furthermore, if lots of people report negative sightings and few people claim positive sightings, it will help them isolate mistakes more easily than if no one reported negative sightings. This could happen when the moon is in the invisible phase (Mahaq) and something else is mistaken for the moon (e.g. Venus Crescent)!
"It is a misunderstanding to consider only [moon] sighting is Sunnah but sighting and reporting, both are together [as part of the Sunnah]", Mufti Yusuf Sacha (13/9/2020). [MP3 Audio]
Note that it is recommended to take photos of the horizon before and after sunset (with or without the Hilal) for supportive evidence. It could easily show the clarity of the horizons and weather conditions. However, observation reports can be submitted without photos, if they are not available!
Where should people submit the Hilal sighting reports?
Many organisations and individuals frequent the ICOUK website for reliable Hilal reports. Therefore, you should send your Hilal Sighting reports to the ICOUK website (Send Observation Report) from the field in the first instance, which should take only about 1 - 2 mins the most (if you already have your login saved in your device). You should also SHARE it with your organisation (if any) and moon sighting groups on Social Media, as appropriate.

It is well-known amongst Muslim scholars and moon sighting experts that a lunar month is either 29 or 30 days long. It is never less than 29 days or more than 30 days long.
According to Islamic tradition, Muslims always look for the crescent moon (Hilal) on the 29th lunar date and if it’s not sighted then 30 days of the month is to be completed. This method works well with equatorial countries/locations where clear skies are the norm and cloudiness is an exception.
Perhaps, what is not so well-known is the fact that a lunar year has about 6 months that are 29 days long and all others are 30 days long, making a lunar year of 354 days long approximately, which is 11 days shorter than a solar year (hence Ramadan rotating through all the seasons).
The normal moon sighting practice of equatorial countries does not work in the case of the UK due to the prolonged adverse weather conditions throughout the year. These persistent adverse UK weather conditions are caused by the high and low pressures of the surrounding oceans.
Therefore, if the UK Muslims keep on completing 30-days month (as per tradition) then after about 6 months, the month length will become less than 29th days, which is not allowed in an Islamic (Hijri) Calendar system.
Similarly, if the month is prematurely ended on 29th day due to human errors (or by accepting erroneous foreign news), the future months are likely to be more than 30 days long, which is also not allowed. It is either 29 or 30 days and not less than 29 or more than 30 days.
Furthermore, the Fiqh scholars have stated that the Hilal must be seen on the 30th day (in clear sky) otherwise the start must have been wrong and if that's Ramadan then a Fast must be kept on the 31st day. In the case of the Hilal being sighted on the 28th date, a Qadha fast must be kept after Eid (see references).
Therefore, it is necessary for the UK Muslims to look for the Hilal on both 29th and the next day (30th or 1st) to minimise errors, especially in adverse weather conditions of the UK.
Besides, the above data may inform if it’s possible to rely totally on UK moon sighting reports or not in the future, without borrowing conflicting foreign news, as is the present practice.
Note that the Muslims of the Indian Subcontinent (where most UK Muslims are from), usually start Ramadan/Shawwal almost every year after sighting a 30+ hours old moon in clear sky conditions, hence it is easily seen by the naked eye.
Any sighting of a moon less than 24 hours old, especially in cloudy weather will require the help of optical aids (e.g. binoculars), which has been permitted by many UK scholars.

This article was written for Ramadan 1437 Hilal and has been updated for Shawwal 1446 Hilal
The crescent visibility map on the ICOUK website shows that on Saturday 29th March 2025, the Shawwal 1446 AH crescent moon (Hilal) will not be possible to be sighted in the UK/Morocco region by the naked eye (RGO/Yallop Code E-F).
However, many people will be looking for the Shawwal Hilal on that date (29th Ramadan/ Ummul Qura) to confirm if the moon can or cannot be sighted by the human eye.
This confirmation will ensure that the decision to complete 30-days of the month (for Ummul Qura followers) is based on negative sighting reports and not entirely based on visibility maps or scientific data.
Therefore, it is important to report negative sightings, just as it is important to report positive sightings, which will help remove any erroneous sighting reports, i.e. if hundreds of people could not sight the moon (in a clear sky), how can a few peoples' claims to see it (implying those hundreds of people are all blind!)?
The Quran states that the moon goes through stages (36:39) and the Tafsir [1] explains there are visible phases of the moon when it can be seen and there are invisible phases of the moon (Mahaq) when it cannot be seen (for 1 or 2 days in each month).
The predicted crescent visibility maps and related scientific data, simply confirm the visible and invisible phases of the moon, which is consistent with the teaching of the Quran and Ahadith.
Compare the use of Google Maps calculation to measure the distance when the prayer of a traveller becomes shortened (Qasar/قصير). Would you consider it against the Sunnah to use Google maps?
What about using a car to travel to the Masjid for prayers or an aeroplane to go to Hajj/Umrah? Would you consider them to be against the Sunnah too (instead of riding a Camel)?
Therefore, it is not against Sunnah to use the Crescent Visibility Maps. In fact, it is commendable to do so, because the intention of the Shariah is not to start a month in doubt [2], but with certainty which the visibility maps help to achieve.
Furthermore, the visibility maps help the Hilal Committees to determine the veracity/accuracy of the witness statements. So, it does not at all go against the Sunnah (as it is not used to determine when Ramadan should start or end) but rather it is one of the many factors the Hilal Committees can take into consideration when accepting any witness statements.

[This article from ISNA website from May 2000 is included for academic interests only - Editor]
ISLAMIC SOCIETY OF NORTH AMERICA
Fiqh Council of North America's Position for Eid-al-Adha
Element of Place Is Dominant in Eid al Adha
In studying the question of determining the dates of the Eid celebrations, the Fiqh Council of North America considers a number of factors from the Shari‘ah perspective. Chief among these is the concept of unity. Allah Most High said: This is your Ummah. It is one Ummah; and I am your Lord. So worship Me! (21:92). From this verse the concepts of unity and group worship are clearly shown to be at the core of the din of Islam. Thus, regardless of how circumstances may change with the passing of time, Muslims must do their utmost to maintain their unity. On the continent of North America, where Muslim unity is closely linked to Muslim identity, this factor is all the more important.
We ask Allah to bestow His mercy on all who stay at home. And we ask all Muslims to heed Allah in respect of the hajj performed by the hajjis, and to show consideration for the unity of this Ummah, and not to spread dissension. Likewise, we ask Allah to show us the truth as the truth and falsehood as falsehood, and to protect us from all evil.
Allah Most High has replaced the many festivals practiced by the Arabs during the period of ignorance with two Eids for Muslims. Each Eid is linked with an essential act of worship. About the end of fasting, Allah said: Allah intends every facility for you; He does not want to put you to difficulties. He wants you to complete the prescribed period, and to glorify Him in that He has guided you; and perchance you shall be grateful (2:185). About the end of hajj He said: Then let them complete the rites prescribed for them, perform their vows, and again circumambulate the Ancient House (22:29)
The first of these two verses is considered the legal basis for the Eid al Fitr. The Eid al Adha, on the other hand, was established as a celebration for completing the rites of hajj and the move from Arafat. Allah said: So when you have accomplished your holy rites, celebrate the praises of Allah (2:200).
The classical jurists determined that the two Eids, Eid al Fitr and Eid al Adha, are determined by factors relating to time and place, with the difference that the element of time and place, with the difference that the element of time in the Eid al Fitr is the dominant element, whereas the element of place is the dominant element in regard to the Eid al Adha, which is linked to the place of hajj (the sacred places in Makkah, Mina, Arafat, etc.) In both celebrations there are two kinds of celebrants; those who celebrate their having performed acts of Ibadah, and those who celebrate the ibadah performed by others. In the case of the Eid al Adha, the dominant element is place, and during this Eid those celebrating their own performance of the ibadah are located in the sacred places. Therefore, those Muslims who are not themselves at the sacred places at that particular time are actually sharing in the celebration of this great act of ibadah, and, as such, should follow the lead of those who celebrate it for themselves in the sacred places. Of course, in the past Muslims outside the sacred places had no way of knowing when the celebrations were held in the sacred places, and had to rely on their local calendar. With modern communications, however, this is no longer necessary.
The classical jurists of Islam have held that once the dates for the pilgrimage have been established, they may not be disputed. Some scholars have stated that if someone is certain that he/she has sighted the crescent, and is convinced that the announced dates for the pilgrimage are incorrect, that person may not publicize or announce his sighting and thereby spread dissension among the pilgrims. This is because such behavior will lead to disruption between the hajjis, and to the negation of their hajj, which is haram.
Among the great scholars of the past to subscribe to this view were al Imam Muslim, Ibn Taymayah and al Imam al Nawawi. Some scholars have even stated that the person who announces a correct but contradictory sighting should have his/her hajj negated. Rather, they opine, such a person should remain silent about his/her conviction about the error.
We would like to take this opportunity to remind all Muslims that the hajj is one of the pillars of Islam, an example of the equality in which Islam holds all humankind, and a symbol of the unity that binds the entire ummah together as one.
In view of the above considerations, the Fiqh Council requests all Muslims in the United States and Canada to celebrate the Eid with the hajjis on the same day that they stand in prayer in the masjid al Heef at Mina, celebrating the praises of Allah for the bounty that He has granted them. In this way our prayers may include them, and their prayers may include us. [May 2000]
PLEASE NOTE: The above ruling was changed in a ISNA's conference (on Moon Sighting) in November 2000 to actual moon sighting, but subsiquesntly changed back to following Saudi Arabia for Eid.
