Musnad Abi Ya'la 6934 — she said (in the presence of Umm Musa, may)

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she said (in the presence of Umm Musa, may Allah have mercy on her): "By the One by whom oaths are sworn! Sayyiduna Ali (may Allah be pleased with him) was the closest of all people to the Messenger of Allah (peace and blessings be upon him) in terms of the last meeting and nearness." She said: On the day the soul of the Messenger of Allah (peace and blessings be upon him) was taken, he (peace and blessings be upon him) was in the house of Sayyidah Aishah (may Allah be pleased with her), and the Messenger of Allah (peace and blessings be upon him) kept asking, morning after morning, again and again: "Has Ali come?" Sayyidah Umm Salamah (may Allah be pleased with her) said: I think he (peace and blessings be upon him) had sent him somewhere on some errand. Then he came a little later, and we sensed that he (peace and blessings be upon him) had some private matter to discuss with him, so we all went out of the room and sat by the door, and I was the nearest of them all to the door. Then Sayyiduna Ali (may Allah be pleased with him) bent over him (peace and blessings be upon him), and he (peace and blessings be upon him) began to speak with him in whispers and confidential talk. Then he (peace and blessings be upon him) passed away on that same day.
