Last will for Hasan and Husayn
Nahj al-Balāgha|Volume 1|Book 2|Chapter 47
انْظُرُوا إِذَا أَنَا مِتُّ مِنْ ضَرْبَتِهِ هَذِهِ، فَاضْرِبُوهُ ضَرْبَةً بِضَرْبَةٍ، وَلَا يُمَثَّلُ [تُمَثِّلُوا] بِالرَّجُلِ، فَإِنِّي سَمِعْتُ رَسُولَ اللهِ (صلى الله عليه وآله) يَقُولُ : «إِيَّاكُمْ وَالْمُثْلَةَ وَلَوْ بَالْكَلْبِ الْعَقُورِ».
Wait till I die by his (Ibn Muljam’s) existing stroke. Then strike him one stroke for his stroke and do not dismember the limbs of the man, for I have heard the Messenger of Allah صلى الله عليه وعلى آله وسلم saying, “Avoid cutting limbs even though it may be a rabid dog.”
