Sayyidah Umm Salamah (may Allah be pleased with her) said: When the Prophet (peace and blessings be upon him) proposed marriage to me, I said: I have three traits: I am advanced in age, I am a woman with young children, and I am a woman of intense jealousy. The Prophet (peace and blessings be upon him) said: "As for the children, their matter rests with Allah and His Messenger; as for the jealousy, I will supplicate to Allah to remove it from you; and as for age, I am older than you." So the Prophet (peace and blessings be upon him) married her while she was nursing her daughter Zaynab bint Abi Salamah. The Prophet (peace and blessings be upon him) would come and go but not approach her, and when he came in he would play with her daughter. Then Ammar bin Yasir (may Allah be pleased with him) came in and said: Where is this daughter of yours who has kept the family of the Prophet (peace and blessings be upon him) occupied? So he took her and arranged for her to be nursed in Sa'y. Then the Prophet (peace and blessings be upon him) came in and said: "Where is Zunab?" A woman said: Ammar came and took her away, and arranged for her to be nursed in Sa'y. Then the Prophet (peace and blessings be upon him) went in to his wife.
