NASAI-KUBRA 8378:
from Saʿd —
[Machine] When the Messenger of Allah ﷺ went out to Tabuk, Ali also went out accompanying him. He started crying and said, "O Messenger of Allah, are you leaving me with the women and children?" The Prophet ﷺ said to Ali, "O Ali, are you not satisfied with being to me as Harun was to Musa, except that there is no Prophethood after me?"
الكبرى للنسائي ٨٣٧٨:
عن سعد —
لَمَّا خَرَجَ رَسُولُ اللهِ ﷺ إِلَى تَبُوكَ خَرَجَ عَلِيٌّ يُشَيِّعُهُ فَبَكَى وَقَالَ يَا رَسُولَ اللهِ أَتَتْرُكُنِي مَعَ الْخَوَالِفِ؟ فَقَالَ النَّبِيُّ ﷺ يَا عَلِيُّ «أَمَا تَرْضَى أَنْ تَكُونَ مِنِّي بِمَنْزِلَةِ هَارُونَ مِنْ مُوسَى إِلَّا النُّبُوَّةَ»
