Abd al-Rahman bin Hanzalah (may Allah be pleased with him) narrates from his maternal aunt Sakinah bint Hanzalah (may Allah be pleased with her), who was in Quba married to her paternal cousin, who then died. She said: Abu Ja'far Muhammad bin Ali (may Allah have mercy on him) came to me while I was in my waiting period. He greeted me with salam and asked: "O daughter of Hanzalah, how are you this morning?" I said: "Well, and may Allah keep you well." He said: "I am related to the Messenger of Allah (peace and blessings be upon him) and to Ali (may Allah be pleased with him); I have my right in Islam and my standing among the Arabs." I, that is, Sakinah bint Hanzalah, said: "O Abu Ja'far, may Allah forgive you! You are a man from whom (knowledge) is taken and from whom narrations are reported, and you are proposing to me during my waiting period?" He said: "I have not done so; I only mentioned my kinship with the Messenger of Allah (peace and blessings be upon him)." Then he said: The Messenger of Allah (peace and blessings be upon him) visited Umm Salamah bint Abi Umayyah bin al-Mughirah al-Makhzumiyyah (may Allah be pleased with her), who had been widowed by Abu Salamah (may Allah be pleased with him), who was her paternal cousin. He (peace and blessings be upon him) kept mentioning to her his standing with Allah, until the mat left marks on his palm (from how heavily he leaned on it). "That was not a proposal."
