When Ibn Muljim struck ʿAli ؓ , ‘Ali said: Do with him what the Messenger of Allah ﷺ wanted to be done with a man who wanted to kill him. He said: ʿKill him, then burn him.ʿ
عَلِيٌّ افْعَلُوا بِهِ كَمَا أَرَادَ رَسُولُ اللهِ ﷺ أَنْ يَفْعَلَ بِرَجُلٍ أَرَادَ قَتْلَهُ فَقَالَ اقْتُلُوهُ ثُمَّ حَرِّقُوهُ
