al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
فَأَنَا أَبُو حَسَنٍ قَاتِلُ جَدِّكَ وَخَالِكَ وَأَخِيكَ شَدْخاً يَوْمَ بَدْر، وَذَلِكَ السَّيْفُ مَعِي، وَبِذلِكَ الْقَلْبِ أَلْقَى عَدُوِّي، مَا اسْتَبْدَلْتُ دِيناً، وَلَا اسْتَحْدَثْتُ نَبِيّاً، وَإنِّي لَعَلَى الْمِنْهَاجِ الَّذِي تَرَكْتُمُوهُ طَائِعِينَ، وَدَخَلْتُمْ فِيهِ مُكْرَهِينَ.
I am Abu’l-Ḥasan who killed your grandfather [2], your brother [3] and your uncle [4] by cutting them to pieces on the day of Badr. The same sword is with me and I meet my adversary with the same heart. I have not altered the religion nor put up any new prophet. I am surely (treading) on that very highway which you had willingly foresaken (in the beginning) and then adopted per force.
