And when Saul marched out with his army, he warned: "Allah is going to put you to a test by the side of a river: whoso drinks of its water shall cease to be my companion: he alone shall be~my companion who does not quench his thirst with its water: one may, however, take except a few, drank their fill of it. Afterwards when Saul, and those who had believed with him, crossed the river and advanced forward, the former said to Saul, "We have no power left this day to fight against Goliath and his hosts." But those who believed that one Day they shall meet Allah, declared, "lt has often been that a small host has, by Allah's grace, overcome a big host: for Allah is with those who show fortitude." 249 When they advanced to meet Goliath and his forces, they prayed: "Our Lord! Pour out constancy on us and make our steps firm: Help us against those that reject faith." 250 So they routed them by the command of Allah; and Dawud (David) slew Jalut, and Allah gave him the kingdom and wisdom, and taught him all whatever He willed; and if Allah does not ward off some men by others, the earth will be destroyed, but Allah is Most Munificent towards the entire creation. 251 THESE are God's messages: We convey them unto thee, [O Prophet,] setting forth the truth - for, verily, thou art among those who have been entrusted with a message. 252 ۞ We gave some of Our Messengers preference over others. To some of them God spoke and He raised the rank of some others. We gave authoritative proofs to Jesus, son of Mary, and supported him by the Holy Spirit. Had God wanted, the generations who lived after those Messengers would not have fought each other after the authority had come to them. But they differed among themselves, some of them believed in the authority and others denied it. They would not have fought each other had God wanted, but God does as He wills. 253
