to his son Muhammad b. al-Hanafiyya when he gave him the standard in the Battle of the Camel, mountains may move from their position but you should not move from yours. Grit your teeth. Lend to Allah your head [i.e. give yourself to Allah]. Plant your feet firmly in the ground. Have your eye on the remotest foe and lower your gaze, and know that victory is from Allah, the Glorified.'
