al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
وَلَعَمْرِي، يَا مُعَاوِيَةُ، لَئِنْ نَظَرْتَ بِعَقْلِكَ دُونَ هَوَاكَ لَتَجِدَنِّي أَبْرَأَ النَّاسِ مِنْ دَمِ عُثْمانَ، وَلَتَعْلَمَنَّ أَنِّي كُنْتُ فِي عُزْلَة عَنْهُ، إِلَّا أَنْ تَتَجَنَّى فَتَجَنَّ مَا بَدَا لَكَ! وَالسَّلَامُ.
By my life, O Mu‘āwiyah, if you see with your intellect without any passion you will find me the most innocent of all in respect of ‘Uthmān’s blood and you will surely know that I was in seclusion from him, unless you conceal what is quite open to you (and accuse me of a crime I have not committed). Then you may commit any outrage (on me) as you wish and that is an end to the matter.
