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 So, when they went forth against Goliath and his hosts, they said, 'Our Lord, pour out upon us patience, and make firm our feet, and give us aid against the people of the unbelievers!' 250 By the will of God they defeated them, and David killed Goliath, and God gave him kingship and wisdom, and taught him whatsoever He pleased. If God did not make men deter one another this earth would indeed be depraved. But gracious is God to the people of the world. 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 ۞ And those Messengers, some We have preferred above others; some there are to whom God spoke, and some He raised in rank. And We gave Jesus son of Mary the clear signs, and confirmed him with the Holy Spirit. And had God willed, those who came after him would not have fought one against the other after the clear signs had come to them; but they fell into variance, and some of them believed, and some disbelieved; and had God willed they would not have fought one against the other; but God does whatsoever He desires. 253
