Sahih Muslim Book 25, Hadith 28
It was mentioned before A'isha that will had been made (by the Holy Prophet) in favour of 'Ali (as the Prophet's first caliph), whereupon she said: When did he make will in his favour? I had been providing support to him (to the Holy Prophet) with my chest (or with my lap). He asked for a tray, when he fell in my lap (relaxing his body), and I did not realise that he had breathed his last. When did he make any will in his ('Ali's) favour?
This hadith has been narrated on the authority of A'mash with the same chain of transmitters.
Thursday, (and then said): What is this Thursday? He then wept so much that his tears moistened the pebbles. I said: Ibn 'Abbas, what is (significant) about Thursday? He (Ibn 'Abbas) said: The illness of Allah's Messenger (ﷺ) took a serious turn (on this day), and he said: Come to me, so that I should write for you a document that you may not go astray after me. They (the Companions around him) disputed, and it is not meet to dispute in the presence of the Apostle. They said: How is lie (Allah's Apostle)? Has he lost his consciousness? Try to learn from him (this point). He (the Holy Prophet) said: Leave me. I am better in the state (than the one in which you are engaged). I make a will about three things: Turn out the polytheists from the territory of Arabia; show hospitality to the (foreign) delegations as I used to show them hospitality. He (the narrator) said: He (Ibn Abbas) kept silent on the third point, or he (the narrator) said: But I forgot that.
This hadith was mentioned through another chain.
