The Chachnāma (Fatḥnāma-yi Sind) 35.2.5

35.2.5

If, after the coming up of the enemy and the commencement of battle, he turns his face, the soldiers will be disheartened, and they will run away, and our enemy will then be more pressing and powerful. Whoever so turns his face will incur disgrace, and die the death of a coward, and be liable to the torture of the next world.” On hearing this proclamation, no one returned, except 3 persons,—one who said that he had a daughter at home and there was no other person to support her; another, who said that he had an old mother, who had no other relation to bury her, when she died; and a third, who said that he had a heavy debt on him and there was none else to discharge it. Muhammad Kasim permitted them to go away. The rest of the people remained with him unanimously. When the bridge was ready, the army began to pass over it. All went over safely except one person by name ‘Imrán, belonging to the family of Baníy Hanzalah who fell down into the river while crossing it and was drowned. The army of Islám then marched on, till it came near the fort of Bet. All the horsemen were so covered with coats of mail that they appeared to be, as it were, drowned in iron. Some parties were told off to different directions for reconnoitring. A ditch was dug round the camp, and the luggage (of the army) was (carefully) deposited. Muhammad Kásim started from the fort of Bet towards Ráór and soon arrived at a town called Jitor. There was a lake between Raor and Jitor.
