Sahih Al Bukhari (439)

عن سهل بن سعد قال: جاء رسول الله صلى الله عليه وسلم بيت فاطمة، فلم يجد عليا في البيت، فقال: (أين ابن عمك). قالت: كان بيني وبينه شيء، فغاضبني فخرج، فلم يقل عندي، فقال رسول الله صلى الله عليه وسلم لإنسان: (انظر أين هو). فجاء فقال: يا رسول الله، هو في المسجد راقد، فجاء رسول الله صلى الله عليه وسلم وهو مضطجع، قد سقط رداؤه عن شقه، وأصابه تراب، فجعل رسول الله صلى الله عليه وسلم يمسحه عنه ويقول: (قم أبا تراب، قم أبا تراب).

Sahl ibn Sa`d (may Allah be pleased with him) narrated: Allah’s Messenger (peace be upon him) went to Fatima’s house but did not find ‘Ali there. So, he asked, “Where is your cousin?” She replied: “There was something between us and he got angry with me and went out. He did not sleep (mid-day nap) in the house.” Allah’s Messenger (peace be upon him) asked a person to look for him. That person came and said, “O Allah’s Messenger! He (‘Ali) is sleeping in the mosque.” Allah’s Messenger (peace be upon him) went there and ‘Ali was lying. His upper body cover had fallen down to one side of his body and he was covered with dust. Allah’s Messenger (peace be upon him) started cleaning the dust from him saying: “Get up! O Abu Turab. Get up! O Abu Turab (literally means: O father of dust).
