[Machine] The Messenger of Allah ﷺ said to Ali when he intended to fight, "It is necessary that you be steadfast or be steadfast." So he left him and people said, "He left him for something he disliked." Ali heard about it and went to the Messenger of Allah ﷺ and informed him. Then the Messenger of Allah ﷺ laughed and said, "O Ali, would you not be pleased to be to me like Aaron was to Moses, except that there is no prophet after me?"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِعَلِيٍّ حِينَ أَرَادَ أَنْ يَغْزُوَ «إِنَّهُ لَابُدَّ مِنْ أَنْ تُقِيمَ أَوْ أُقِيمَ» فَخَلَفَهُ فَقَالَ نَاسٌ مَا خَلَفَهُ إِلَّا لِشَيْءٍ كَرِهَهُ فَبَلَغَ ذَلِكَ عَلِيًّا فَأَتَى رَسُولَ اللهِ ﷺ فَأَخْبَرَهُ فَتَضَاحَكَ ثُمَّ قَالَ «يَا عَلِيُّ أَمَا تَرْضَى أَنْ تَكُونَ مِنِّي بِمَنْزِلَةِ هَارُونَ مِنْ مُوسَى إِلَّا أَنَّهُ لَيْسَ نَبِيٌّ بَعْدِي»
