Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he said: "The prophets of the Children of Israel used to lead them politically as well. Whenever a prophet passed away, another prophet would succeed him. But there will be no prophet after me." They asked: O Messenger of Allah! Then what will happen? He said: "There will be caliphs (deputies) and they will be many. Fulfill their rights, and ask Allah for your own rights."
