One of the dearest of Ali's names to him was indeed Abu Turab, and he used to be delighted when called by it. No one had given him this name except the Prophet ﷺ.One day Ali became upset with Fatimah, so he went out and lay down by the wall of the mosque. The Prophet ﷺ came looking for him, and someone said, "He is over there, lying down against the wall."The Prophet ﷺ came to him and found his back covered with dust. The Prophet ﷺ began to wipe the dust off his back, saying, "Sit up, Abu Turab."
حدثنا خالد بن مخلد حدثنا سليمان قال حدثني أبو حازم
إن كانت أحب أسماء علي رضي الله عنه إليه لأبو تراب وإن كان ليفرح أن يدعى بها وما سماه أبو تراب إلا النبي ﷺ غاضب يوما فاطمة فخرج فاضطجع إلى الجدار إلى المسجد فجاءه النبي ﷺ يتبعه فقال هو ذا مضطجع في الجدار فجاءه النبي ﷺ وامتلأ ظهره ترابا فجعل النبي ﷺ يمسح التراب عن ظهره ويقول اجلس يا أبا تراب
