About those who accused him of killing Uthman
Nahj al-Balāgha|Volume 1|Book 1|Chapter 22
[ذم الناكثين] أَلاَ وإِنَّ الشَّيْطَانَ قَدْ ذَمَّرَ حِزْبَهُ وَاسْتَجْلَبَ جَلَبَهُ لِيَعُودَ الجَوْرُ إِلَى أَوْطَانِهِ، وَيَرْجِعَ البِاطِلُ إِلَى نِصَابِهِ وَاللهِ مَا أَنْكَرُوا عَلَيَّ مُنْكَراً، وَلاَ جَعَلُوا بَيْنِي وَبَيْنَهُمْ نَصِفاً
Beware! Satan has certainly started instigating his forces and has collected his army in order that oppression may reach its extreme ends and wrong may come back to its position. By Allāh they have not put a correct blame on me, nor have they done justice between me and themselves.
