At the Battle of Siffin, Ali entrusted the flag of command to his son Muhammad Hanifa. Ali issued him the following instructions: "O son, let mountains move from their places, but you should not move from the place that has been assigned to you in the battlefield. Install your feet firmly on the ground as though a nail has been driven into it. Let your one jaw of teeth rest firmly on the other jaw. Keep an eye on the rear of your enemy. Enter the battle with firm determination that you have sold your head to God. With all this, always think that success lies in the hands of God. Above all never raise your hand against the sick, women, the aged, and children. Even if they abuse you, it behooves you to give them refuge. Never mutilate the limbs of the enemy or any other person. Give decent burial to the dead bodies of your enemies."
