مسند أحمد

It was narrated that ‘Ali (رضي الله عنه) said: It was said: O Messenger of Allah (ﷺ), who should be appointed in charge after you are gone? He said: “If you appoint Abu Bakr, you will find him trustworthy and uninterested in worldly gains, seeking the Hereafter. If you appoint ‘Umar, you will find him strong and trustworthy and not fearing the blame of anyone for the sake of Allah. If you appoint Ali Which I do not think you will do you will find him a guide and guided, he will take you on the straight path.”
