al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
فَوَاللهِ لَوْ لَمْ يُصِيبُوا مِنَ الْمُسْلِمِينَ إِلاَّ رَجُلاً وَاحِداً مُعْتَمِدِينَ لِقَتْلِهِ، بِلاَ جُرْم جَرَّهُ، لَحَلَّ لي قَتْلُ ذلِكَ الْجَيْشِ كُلِّهِ، إِذْ حَضَرُوهُ فَلَمْ يُنْكِرُوا، وَلَمْ يَدْفَعُوا عَنْهُ بِلِسَان وَلاَ يَد. دَعْ مَا أَنَّهُمْ قَدْ قَتَلُوا مِنَ الْمُسْلِمِينَ مِثْلَ الْعِدَّةِ الَّتِي دَخَلُوا بِهَا عَلَيْهِمْ!
By Allāh, even if they had wilfully killed only one individual from among the Muslims without any fault, it would have been lawful for me to kill the whole of this army because they were present in it but did not disagree with it nor prevented it by tongue or hand, not to say that they killed from among the Muslims a number equal to that with which they had marched on them.
