And when Saul went forth with the soldiers, he said, "Indeed, Allah will be testing you with a river. So whoever drinks from it is not of me, and whoever does not taste it is indeed of me, excepting one who takes [from it] in the hollow of his hand." But they drank from it, except a [very] few of them. Then when he had crossed it along with those who believed with him, they said, "There is no power for us today against Goliath and his soldiers." But those who were certain that they would meet Allah said, "How many a small company has overcome a large company by permission of Allah. And Allah is with the patient." 249 Accordingly, when they marched forward to fight with Goliath and his hosts, they prayed, "Our Lord, bless us with fortitude, make firm our foothold and give us victory over the unbelieving host." 250 And thereupon, by God's leave, they routed them. And David slew Goliath; and God bestowed upon him dominion, and wisdom, and imparted to him the knowledge of whatever He willed. And if God had not enabled people to defend themselves against one another, corruption would surely overwhelm the earth: but God is limitless in His bounty unto all the worlds. 251 These are the portents of Allah which We recite unto thee (Muhammad) with truth, and lo! thou art of the number of (Our) messengers; 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
