Majma al-Zawaid — Hadith 14605

Afif al-Kindi narrates: I was a merchant. I came to Makkah and went to al-Abbas bin Abd al-Muttalib to buy some trade goods from him, for he too was a merchant. The narrator says: By Allah, I was with him at Mina when a man came out of a tent close by. He looked towards the sky, and when he saw that the sun had passed its zenith, he stood up and began to pray. Then a woman came out of that tent, the same tent from which the man had come out, and she stood behind him and began to pray. Then a boy came out, also from the same tent; he was close to puberty, and he stood with him and began to pray. I asked al-Abbas: O Abbas, who is this? He said: This is Muhammad, the son of my brother Abdullah bin Abd al-Muttalib. I asked: Who is this woman? He said: This is his wife, Khadijah bint Khuwaylid. I asked: Who is this boy? He said: This is Ali bin Abi Talib, his cousin. I said: What are they doing? He said: They are praying. He claims that he is a prophet, and so far no one has followed him except his wife and this young cousin of his. He also claims that the treasures of Chosroes and Caesar will be opened for him. The narrator says: Afif was a cousin of al-Ash'ath bin Qays. Later he accepted Islam, and his Islam was good. He said: If Allah Almighty had granted me Islam on that day, I would have been the second person to accept Islam along with Sayyiduna Ali bin Abi Talib (may Allah be pleased with him).
Ahmad recorded it, Abu Ya'la recorded something similar, and al-Tabarani recorded it with various chains; the narrators of Ahmad are thiqat (trustworthy). (Allamah al-Haythami says:) I say: The hadith of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) to the same effect will come in the chapter on the virtues of Sayyidah Khadijah (may Allah be pleased with her).
