Mountains [2] may move from their position but you should not move from yours. Grit your teeth. Lend to Allāh your head (in fighting for Allāh, give yourself to Allāh). Plant your feet firmly on the ground. Have your eye on the remotest foe and close your eyes (to their numerical majority). And keep sure that succour is but from Allāh, the Glorified.
