(4) باب مِنْ فَضَائِلِ عَلِيِّ بْنِ أَبِي طَالِبٍ رضى الله عنه
Sa'd b. Abi Waqqas reported that Allah's Messenger (ﷺ) left 'Ali b. Abi Talib behind him (as he proceeded) to the expedition of Tabuk, whereupon he ('Ali) said:
Allah's Messenger, are you leaving me behind amongst women and children? Thereupon he (the Holy Prophet) said: Aren't you satisfied with being unto me what Aaron was unto Moses but with this exception that there would be no prophet after me?
