Narrated Abu Hazim: A man came to Sahl bin Sa`d and said, "This is so-and-so," meaning the Governor of Medina, "He is calling `Ali bad names near the pulpit." Sahl asked, "What is he saying?" He (i.e. the man) replied, "He calls him (i.e. `Ali) Abu Turab." Sahl laughed and said, "By Allah, none but the Prophet called him by this name and no name was dearer to `Ali than this." So I asked Sahl to tell me more, saying, "O Abu `Abbas! How (was this name given to `Ali)?" Sahl said, "`Ali went to Fatima and then came out and slept in the Mosque. The Prophet asked Fatima, "Where is your cousin?" She said, "In the Mosque." The Prophet went to him and found that his (i.e. `Ali's) covering sheet had slipped of his back and dust had soiled his back. The Prophet started wiping the dust off his back and said twice, "Get up! O Abu Turab (i.e. O. man with the dust).

Narrated Sahl bin Sa`d: Allah's Apostle 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 (midday nap) in the house." Allah's Apostle asked a person to look for him. That person came and said, "O Allah's Apostle! He (Ali) is sleeping in the mosque." Allah's Apostle 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 Apostle started cleaning the dust from him saying: "Get up! O Aba Turab. Get up! O Aba Turab (literally means: O father of dust).

Narrated Sahl bin Sa`d: The most beloved names to `Ali was Abu Turab, and he used to be pleased when we called him by it, for none named him Abu Turab (for the first time), but the Prophet. Once `Ali got angry with (his wife) Fatima, and went out (of his house) and slept near a wall in the mosque. The Prophet came searching for him, and someone said, "He is there, Lying near the wall." The Prophet came to him while his (`Ali's) back was covered with dust. The Prophet started removing the dust from his back, saying, "Get up, O Abu Turab!"

Narrated Sahl bin Sa`d: There was no name dearer to `Ali than his nickname Abu Turab (the father of dust). He used to feel happy whenever he was called by this name. Once Allah's Apostle came to the house of Fatima but did not find `Ali in the house. So he asked "Where is your cousin?" She replied, "There was something (a quarrel) between me and him whereupon he got angry with me and went out without having a midday nap in my house." Allah's Apostle asked a person to look for him. That person came, and said, "O Allah's Apostle! He (Ali) is sleeping in the mosque." So Allah's Apostle went there and found him lying. His upper body cover had fallen off to one side of his body, and so he was covered with dust. Allah's Apostle started cleaning the dust from him, saying, "Get up, O Abu Turab! Get up, Abu Turab!"
