Imam Ali (as): When Imam Ali, peace be upon him, put Ziyad ibn Abih in place of Abdullah ibn Abbas over Fars (in Persia) and its revenues, he had a long conversation with him in which he prohibited him from collecting the land tax before it came due. Therein, he said: Act on justice and keep aloof from violence and injustice because violence will lead them to forsake their abodes while injustice will prompt them to take up arms. Nahj al-Balāgha
