In the war of Saffayn Imam Ali (AS) prayed to God for his enemies by saying: O’ Allah (SWT), protect our blood and theirs, and make peace between us and them, and guide them from going astray to the right path in order that those who are ignorant, can recognize the truth, and those who are fighting the truth are regretful and return to the truth [1].
