Abd al-Malik bin Abi Bakr bin al-Harith bin Hisham relates from his father: When the Prophet (peace and blessings be upon him) went in to Sayyidah Umm Salamah (may Allah be pleased with her), he stayed with her for three days, then he said: "There is no disgrace upon you in the eyes of your family, and if I give you seven days, I will give each of my other wives seven days as well."
