Bilal bin Sa'd narrates from his father, whose companionship is established, who said: I said: O Messenger of Allah, what is (the right) of the caliph after you? He (peace and blessings be upon him) said: "The same as mine, as long as he shows mercy to relatives, does justice in matters of justice, and is fair in distribution."
