When people chose to swear allegiance at Imam’s hand after the murder of Uthman, he said:

Leave me and seek someone else. We are facing a matter with (several) faces and colours, which neither hearts can stand nor intelligence can accept. Clouds are hovering over the sky, and faces are not discernible. You should know that if I respond to you I would lead you as I know and would not care about whatever one may say or abuse. If you leave me then I am the same as you are. It is possible I would listen to and obey whomever you make in charge of your affairs. I am better for you as a counsellor than as chief.
