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 And when they went forth to [face] Goliath and his soldiers, they said, "Our Lord, pour upon us patience and plant firmly our feet and give us victory over the disbelieving people." 250 Consequently, by Allah's grace, they routed the unbelievers, and David killed Goliath; and Allah gave him kingship and wisdom and taught him whatever other things He willed. And if Allah had not been repelling one set of people by means of another, the earth would have been filled with chaos. But Allah is bountiful to the world (and so repels chaos in this way). 251 These are the verses of Allah which We recite to you, [O Muhammad], in truth. And indeed, you are from among the 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
