It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) stood at the grave of his second daughter, who had been married to Uthman (may Allah be pleased with him), and said: "Listen, is there no father of a widow? Is there no brother of a widow? Uthman married her, and if I had ten daughters I would have married them all to Uthman, and I did not make this marriage except by revelation from the heavens." And the Messenger of Allah (peace and blessings be upon him) met Uthman (may Allah be pleased with him) at the door of the mosque and said: "O Uthman, this is Jibril telling me that Allah, the Mighty and Majestic, has married you to Umm Kulthum for the same dowry as Ruqayyah's dowry, and on the same kind of companionship."
