To the people of Kufa when he marched from Medina to Basra
Nahj al-Balāgha|Volume 1|Book 2|Chapter 57
أَمَّا بَعْدُ، فَإِنِّي خَرَجْتُ مِنْ حَيِّي هذَا: إِمَّا ظَالِماً، وَإِمَّا مَظْلُوماً، وَإِمِّا بَاغِياً، وَإِمَّا مَبْغِيّاً عَلَيْهِ.
Now, I have come out of my city either as an oppressor or as the oppressed, either as a rebel or one against whom rebellion has been committed.
