When this verse was revealed - “And warn your tribe (O Muhammad (ﷺ)) of near kindred" [ash-Shu"ara" 26:214] - the Prophet (ﷺ) gathered his family together. Thirty people gathered and ate and drank. Then he said to them: "Who could take care of my debts and promises for me, and he will be with me in Paradise and will be my successor among my family?" A man-Shareek did not name him – said: O Messenger of Allah (ﷺ), you are like an ocean; who could do that? Then he offered that to the members of his family and ‘Ali (رضي الله عنه) said: I will.
