The new moon sighted when some people have already eaten

Amr bin Muhajir says: Muhammad bin Suwayd al-Fihri celebrated Eid al-Fitr or Eid al-Adha one day before the people. Umar bin Abd al-Aziz wrote to him asking the reason. Muhammad wrote back to him that Hizam bin Hakim al-Qurashi had testified before him to having seen the moon. Umar bin Abd al-Aziz wrote to him: "Is he unique among the people, or is he Dhu al-Yadayn?"

Abd al-Karim says: In the time of Umar bin Abd al-Aziz, people testified during the day to having seen the moon, saying: We saw the moon last night. Umar bin Abd al-Aziz said: Whoever has not eaten should complete his fast, and whoever has eaten should refrain from eating and drinking for the rest of the day.

Ibn Jurayj says: I said to Ata: If some people of Makkah begin the morning not fasting, or one or two men begin the morning not fasting, and then after a while someone comes and says that the moon was seen last night, and this news reaches them in the early or the latter part of the day, should they fast the rest of the day or make up that fast later? He said: If they wish, they may go on eating and drinking; fasting the rest of the day is not obligatory upon them.
