The narrator said: I saw Sayyiduna Abu Dharr (may Allah be pleased with him) holding the two doorposts of the door of the Ka'bah, saying: Whoever knows me knows me, and whoever does not know me, I am Abu Dharr al-Ghifari. I heard the Messenger of Allah (peace and blessings be upon him) say: "The example of my household (Ahl al-Bayt) among you is like the ark of Nuh (peace be upon him) among his people: whoever boarded it was saved, and whoever stayed behind from it perished. And (its) example is that of the Gate of Hittah among the Children of Israel."
