Umm Salamah narrated: “One morning Ameer al-Momineen (a.s) came and knocked at our door. God's Prophet (a.s) asked me to get up and open the door. I opened the door, but Imam Ali (a.s) held the door so that it did not open wide and he could not see me. I went to my room and he requested permission to enter and entered the house when permission was granted.”
