Messenger of Allah ﷺ set out for Tabuk. appointing ʿAli as his deputy (in Medina). ʿAli said, "Do you want to leave me with the children and women?" The Prophet ﷺ said, "Will you not be pleased that you will be to me like Aaron to Moses? But there will be no prophet after me."
أَنَّ رَسُولَ اللَّهِ ﷺ خَرَجَ إِلَى تَبُوكَ وَاسْتَخْلَفَ عَلِيًّا فَقَالَ أَتُخَلِّفُنِي فِي الصِّبْيَانِ وَالنِّسَاءِ قَالَ أَلاَ تَرْضَى أَنْ تَكُونَ مِنِّي بِمَنْزِلَةِ هَارُونَ مِنْ مُوسَى إِلاَّ أَنَّهُ لَيْسَ نَبِيٌّ بَعْدِي وَقَالَ أَبُو دَاوُدَ حَدَّثَنَا شُعْبَةُ عَنِ الْحَكَمِ سَمِعْتُ مُصْعَبًا
