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 appeared to Goliath and his soldiers, they said: 'Lord, pour upon us patience. Make us firm of foot and give us victory against the nation of unbelievers' 250 Then they vanquished them by the leave of Allah, and Da'ud slew Jalut, and Allah vouchsafed him dominion, and wisdom and taught him of that which He willed. And, if not for Allah's repelling people, some of them by means of others, the earth surely were corrupted; but Allah is Gracious unto the worlds. 251 These are Allah's revelations, which We are conveying to you accurately. And O Muhammad, most surely you are of those who have been sent as Messengers. 252 ۞ Of these Messengers, We have preferred some above others. To some Allah spoke; and some He raised in rank. We gave (Prophet) Jesus, the son of Mary, clear signs and strengthened him with the Spirit of Purity (Gabriel). Had Allah willed, those who succeeded them would not have fought against one another after the clear verses came to them. But they differed among themselves; some believed, and others disbelieved. Yet had Allah willed, they would not have fought against one another. Allah does whatever He will. 253
