← Previous Hadith If you do not agree to it (at least) say: May Allah curse Abu Turab. Sahl said: There was no name dearer to `Ali than Abu Turab (for it was given to him by the Prophet himself) and he felt delighted when he was called by this name. He (the governor) said to him: Narrate to us the story of his being named as Abu Turab. He said: Allah's Messenger (ﷺ) came to the house of Fatima and he did not find `Ali in the house; whereupon he said: Where is your uncle's son? She said: (There cropped up something) between me and him which had annoyed him with me. He went out and did not rest here. Allah's Messenger (ﷺ) asked a person to find out where he was. He came and said: Allah's Messenger, he is sleeping in the mosque. Allah's Messenger (ﷺ) came to him and found him lying in the mosque and saw that his mantle had slipped from his back and his back was covered with dust and Allah's Messenger (ﷺ) began to wipe it away from him (from the body of Hadrat `Ali) saying: Get up, covered with dust (Abu Turab); get up, covered with dust.
