Chapter 13(a) - Matters about which Amir al-Mu’minin عليه السلام, Recommended at the Time of War

3. In Hadith narrated from ‘Abd al-Rahman ibn Jundab from his father who has said the following: “Amir al-Mu’minin عليه السلام, in every battlefield we faced our enemies issued his commandments and said, ‘You must not fight the people before they attack you; you by the grace of Allah possess authority and good cause. Your allowing them to attack you first is another valid point in support of the good cause. When you defeat them you must not pursue the fleeing, you must not hurt the wounded and you must not expose anyone’s privacy.’”
