Musnad Ahmad #752

It was narrated that ‘Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) entered upon me when I was sleeping on the mattress. Al-Hasan or Al-Husain asked for a drink, so the Prophet (ﷺ) went to a young sheep and milked it, then Al-Hasan came to him and the Prophet (ﷺ) told him to wait. Fatimah said: O Messenger of Allah (ﷺ), it is as if he is the dearer of the two to you? He said: “No, but he asked for a drink first.” Then he said: `You and I and these two and this one who is sleeping will be in the same place on the Day of Resurrection.”
