Yazid bin Khumayr (may Allah have mercy on him) says that Sayyiduna Abdullah bin Busr (may Allah be pleased with him) went out with the people on the day of Eid al-Fitr or Eid al-Adha, and he disapproved of the imam's coming late and said: "By this time we used to have already finished."
(b) Hasan al-Basri (may Allah have mercy on him) says that the Prophet (peace and blessings be upon him) would go out for Eid al-Adha and Eid al-Fitr after the sun had fully risen, and would lead the Eid prayer at the beginning of its time. Whoever ate before his (peace and blessings be upon him) prayer and fed his family and neighbours, as is clear in the hadith of Sayyiduna Abu Burdah bin Niyar (may Allah be pleased with him), that was not permissible; that is why the Prophet (peace and blessings be upon him) commanded him to sacrifice again.
