Narrated by Abu Huraira
It is narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) observed: What would you do when the son of Mary would descend amongst you and would lead you as one amongst you? Ibn Abi Dhi'b on the authority of Abu Huraira narrated: Your leader amongst you. Ibn Abi Dhi'b said: Do you know what the words: "He would lead as one amongst you" mean? I said: Explain these to me.
