[2] When in the Battle of Jamal Amīr al-mu’minīn sent Muḥammad ibn al-Ḥanafiyyah to the battle-field, he told him that he should fix himself before the enemy like the mountain of determination and resoluteness so that the onslaught of the army should not be able to displace him, and should charge the enemy with closed teeth because by pressing teeth over the teeth tension occurs in the nerves of the skull as a result of which the stroke of the sword goes amiss, as he said at another place also viz. “Press together the teeth. It sends amiss the edge of the sword.” Then he says, “My child, lend your head to Allāh in order that you may be able to achieve eternal life in place of this one, because for a lent article there is the right to get it back. Therefore, you should fight being heedless of your life, other-wise also if your mind clings to life you will hesitate to advance towards deathly encounters and that would tell upon your reputation of bravery. Look, don’t let your steps falter because the enemy is emboldened at the faltering of steps, and faltering steps fastens the feet of the enemy. Keep the last lines of the enemy as your aim so that the enemy may be overawed with loftiness of your intentions and you may feel ease in tearing through their lives, and their movement should also not remain concealed from you. Look, do not pay heed to their superiority in numbers, otherwise your valour and courage would suffer.” This sentence can also mean that one should not wide open the eyes to be dazzled by the shining of weapons, and the enemy may make an attack by taking advantage of the situation. Also, always bear it in mind that victory is from Allāh. “If Allāh helps you no one can overpower you.” Therefore, instead of relying on material means seek His support and succour.
(Remember O’ ye Believers!) If Allāh helpeth you, none shall over-come you . . . (Qur’ān, 3:159)
