al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
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 (s) saying, “Avoid cutting limbs even though it may be a rabid dog.”
