It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that by the One in whose name oaths are sworn, the last person to meet the Messenger of Allah (peace and blessings be upon him) was Sayyiduna Ali (may Allah be pleased with him). We used to nurse the Messenger of Allah (peace and blessings be upon him) every day, and he would repeatedly ask whether Ali (may Allah be pleased with him) had come. Sayyida (may Allah be pleased with her) says: I think that the Prophet (peace and blessings be upon him) had sent him on some errand, so he came. I thought that the Prophet (peace and blessings be upon him) had some task for him. We left the room and sat near the door. I was the closest to the door of the room. Sayyiduna Ali (may Allah be pleased with him) leaned over the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) began to whisper something confidentially to him, and on that very day the Messenger of Allah (peace and blessings be upon him) passed away. Thus, the last meeting with the Messenger of Allah (peace and blessings be upon him) was with Ali (may Allah be pleased with him).
