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 into the field against Goliath and his hosts they said: Our Lord! Bestow on us endurance, make our foothold sure, and give us help against the disbelieving folk. 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 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 ۞ Of these messengers, We have given something additional among them. There are some to whom God spoke directly and others He exalted in rank. We gave Jesus, son of Mary clear signs, and strengthened him with the holy spirit. Had God pleased, those who succeeded them would not have fought against one another after the clear signs had come to them. But they disagreed among themselves; some believed, while others did not. Yet had God willed, they would not have fought against one another; but God does whatever He wills. 253
