Abu Yaqub al-Khayyat (may Allah have mercy on him) says that once, on the occasion of Eid al-Fitr, I was in Madinah Munawwarah with Mus'ab bin Zubair (may Allah have mercy on him). He sent a messenger to Hazrat Abu Sa'id Khudri (may Allah be pleased with him) to find out what the practice of the Prophet (peace and blessings be upon him) was on the day of Eid. He informed that the Prophet (peace and blessings be upon him) used to perform the prayer before the sermon. Accordingly, Mus'ab (may Allah have mercy on him) also led the prayer before the sermon on that day.
