عثمان بن عفان
In the year 30 AH (after Hijra) or 650 CE, many Muslims living in the city of Kufa were angered over the action of the governor Waleed ibn Uqba (the half brother of Uthman ibn Affan). People went to Mu'awiyah with complaint, the gathering included Malik al-Ashtar and Kumayl ibn Ziyad as well.
