It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that he took hold of the knocker of the door of the Ka'bah and said: Whoever knows me knows me, and whoever does not know me (let him hear): I am Jundub, the Companion of the Prophet (peace and blessings be upon him). I heard the Prophet (peace and blessings be upon him) say: "There is no prayer after Asr until the sun sets, and no prayer after the Fajr prayer until the sun rises, except in Makkah." And he said this three times.
