Hazrat Hakam narrates that when the Messenger of Allah (peace be upon him) married Hazrat Umm Salamah (may Allah be pleased with her), he stayed with her for three days, and then said to her: "If you wish, I will stay with you for seven days, but if I stay for seven days, I will also stay with the other wives for seven days each." Hazrat Hakam was asked who told him this hadith, and he replied that this hadith is well-known among the people of Hijaz.
