    "The Dhul Qada  [1426 AH] Hilaal was clearly visible by naked-eye from Sea Point, Cape Town, 
    this Friday evening of the 2nd December 2005. In Southern Africa the official first day of Dhul 
    Qada will therefore correspond with Saturday, 3rd December 2005. I first observed the very thin 
    crescent [cusps at 4 to 8 o’clock] through 10 x 50 binoculars at 10 minutes after observed local 
    sunset. The crescent became visible to the naked-eye at 20h03 – 18 minutes after local sunset.

  • Germany: ICOP member Mr. Gerhard Ahmad Kaufmann mentioned it was cloudy.

  • UK: ICOP member Mr. Muhammad Afifi al-Akiti said: "Negative sighting. At the end of the 29th day of of the preceeding lunar month (Friday, 2nd December) at the usual moonsighting site, I could not sight the new crescent. The horizon was overcast [ghaym] and it was raining. By the time of Isha', we receive news from Morocco that the new moon was sighted and that the authorities there have declared the new month [thubut al-hilal]. This news is sufficient for us to establish the Dhu l-Qa'dah month in the UK so that the next day, Saturday the 3rd of December, should be the first; instead of the 30th of Shawwal, by default, following the principal rule [dabit] in Fiqh for this case: whenever the crescent is sighted during the night in question anywhere in the East, its sighting follows without doubt in the West, but not the other way round."

  • USA:

    1. ICOP member Mr. Javad Torabinejad said: "This evening (Friday Dec. 2), we sighted the moon in Blacksburg, VA. Immediately after sighting the moon through a pair of 7X50 binoculars, I was able to sight it by naked eye at 5:17 p.m. EST. The horns were on 2:00 and 5:30 o'clock. The sunset was at 5:04."

    2. ICOP member Dr. John Caldwell mentioned that he saw it by binoculars and by naked eye and he said: "I looked rather late, so it could have easily been seen earlier."

    3. ICOP member, Mr. Gulamabbas Khakoo said: "Unable to sight the crescent for the month of Dhul al Qadh from Long Beach, California on Thursday, Dec. 1st and on Friday Dec 2nd 2005. Both days have been very cloudy and impossible to sight due to weather conditions being unfavorable with slight rain."

    4. ICOP member Dr. Muhammad Hafiz said: "I tried to observe the Hilaal on the 1st and 2nd, December, 2005 after sunset in Rose Hall Town, Guyana. Due to the fact that the rainy season started a few days ago Hilaal observation was made impossible."

    5. ICOP member Mr. Bilal Gharaibeh said: "At sunset the clouds thin and had good visibility but after sunset clouds accumulated and it was hard to observe the crescent, Saturday was rainy and didn't try to observe the moon."
