Sayyiduna Ibn Abbas (may Allah be pleased with them both) says: I attended Eid with the Messenger of Allah (peace and blessings be upon him), Sayyiduna Abu Bakr (may Allah be pleased with him), Sayyiduna Umar (may Allah be pleased with him) and Sayyiduna Uthman (may Allah be pleased with him). All of them used to pray before the sermon and then deliver the sermon. He said: The Prophet (peace and blessings be upon him) came down from the pulpit and was seating the men with a gesture of his hand. Then he came through their midst to the women, and Sayyiduna Bilal (may Allah be pleased with him) was with him (peace and blessings be upon him). He (peace and blessings be upon him) said: "O Prophet, when the believing women come to you, pledging allegiance to you" [Surah al-Mumtahanah: 12]. Then, when he (peace and blessings be upon him) had finished with them, he said: "Remain upon this." One woman said, and no one other than her answered him: Yes, O Prophet of Allah!
