The two of us attempted to perform the obligatory sighting tonight in Oxford on 29 Dhu l-Qa'dah or Monday, 10th of December, immediately after Maghrib prayers---in spite of the fact that the crescent is not expected to be visible locally. The local horizon is partly cloudy. There are reports of negative sightings tonight from Morocco and Indonesia, but positive sightings in South Africa. This news of positive sighting to the East of UK (positive--as it does not contradict any physical, scientific facts), despite not being able to sight locally in the UK, makes it sufficient for those in the UK to begin the month of Dhu l-Hijja for the UK to be tomorrow, Tuesday, the 11th of December, by following the default rule [dabit] in Islamic Law in this matter that whenever it is known that the crescent has been positively sighted in the East, local sighting inevitably follows, but not the other way round [mata hasalati r-ru'yatu fi l-sharqi lazima ru'yatuhu fi l-gharbi wa la-'aks]. So 'Id al-Adha, the 10th of Dhu l-Hijja, should properly be in the UK on Thursday, 20th of December. May Allah accept our fasts, prayers and takbirat during this great month!"

  • Guyana: Not Seen: ICOP member Dr. Muhammad Hafiz said: "Myself and the members of Rose Hall Town Masjids and Islamic Center tried to observe the Hilaal after sunset on Monday, 10th December, 2007 in Guyana. Due to extensive rainy clouds on the Western horizon, Hilaal observation was made impossible. Based on the Hilaal visibility curve, the Hilaal for the month of Zul Hijjah will InshaAllah be seen in the American region today, thus Eid Ul Adah will be celebrated in Guyana on Thrusday, 20th December, 2007."

  • USA:

    1. Not Seen: ICOP member Mr. Milad Ali Ershaghi from (Claremont, CA) said: "Local Sunset time was 4:42pm and Moonset time was 5:25pm in Claremont, California, USA.

    3. Not Seen: ICOP affiliate member Hilal Sighting Committee said: "The Hilal was not sighted tonight anywhere in the US. Therefore, we will complete 30 days of Dhul Qa'dah and Eidul Adha will be on Friday, December 21, 2007, Insha Allah."

    Saudi Declares Eid to Be on Wednesday!

    Neglecting all the scientific basics and facts, Saudi had accepted claim of sighting on Sunday 09 December 2007, and announced the beginning of Thul Hijjah to be on Monday 10 December 2007, and hence Eid will be on Wednesday 19 December 2007.

    When to Observe Thul Keadah Waning (OLD) Crescent ?

    The geocentric conjunction (Geocentric New Moon) will occur Inshalla on (Sunday 09 December 2007) at 17:40 UT.

    Sighting the OLD crescent on (Saturday 08 December 2007) and on (Sunday 09 December 2007) is shown in the below graphs using the program Accurate Times by Mohammad Odeh according to Odeh criterion. Where:-

    • It is impossible to see the OLD crescent from the areas located under the red color. Because either the Moon on this day rises after the Sunrise and/or the topocentric conjunction occurs before the Sunrise.
    • The crescent is expected to be seen by optical aid only from the areas located under the blue color.
    • The crescent is expected to be seen by optical aid from the areas located under the magenta color. In these areas the crescent could be seen by naked eye if the atmospheric conditions are superb and the observer is experienced.
    • The crescent is expected to be easily visible by naked eye from the areas located under the green color.
    • The crescent can not be seen from uncolored areas, even though the Moon rises in these locations before the Sunrise and the topocentric conjunction occurs after the Sunrise, but the Moon is not sufficiently illuminated in order to be seen as crescent even by optical aid.
    • Kindly notice that the below graph shows the possibility of seeing the crescent from areas between 60 degrees north of Equator down to 60 degrees south of Equator.
