Sayyidah Umm Salamah (may Allah be pleased with her) narrated: When the Messenger of Allah (peace and blessings be upon him) sent me a proposal of marriage, I said: There are three things in me: I am advanced in age, I am a woman with children, and I am a woman of intense jealousy. The Prophet (peace and blessings be upon him) said: "As for age, I am older than you. As for the children, they are the responsibility of Allah and His Messenger. And as for jealousy, I will pray to Allah to remove it from you." So the Prophet (peace and blessings be upon him) married her. Then, when he went in to her, he said: "You and your family are honoured in my sight. I have not given seven days to any of my wives; but if I give you seven days, I will give seven days to each of my wives as well."
