Forgiveness Of Imam Ali (a.s)

It is written in Sharh Nahjul Balagha that during the battle of Jamal when Amir’ul-Mu’minin (a.s) overpowered Marwan, in spite of the fact that he was his deadly enemy, he did not kill him.
Ibn Abil Hadid has also written in Sharh Nahjul Balagha that in Siffin when the army of Muawiyah obtained control over the river, by the order of Muawiyah, water supply was cut off from the army of Amir’ul-Mu’minin (a.s) and they were not given access to a single drop of water. When the Imam saw that his men were almost dying of thirst, he attacked the opponents and gave them a crushing defeat and snatched the control of the river. Now the Imam’s men said that they would not give a drop of water to the enemy and let them die of thirst. The Imam said, “By Allah! I will not take revenge from them. I will not commit the sin they have committed.” Reference :Akhlaq al-A’imma, Morals & Manners of the Holy Imams
