When Saul set forth with the army he said, "God will test you with a river. Those who drink its water will not be of my people and those who do not even taste the water or who only taste some of it from within the hollow of their hand, will be my friends. They all drank the water except a few of them. When Saul and those who believed in him crossed the river, his people said, "We do not have the strength to fight against Goliath and his army." Those who thought that they would meet God said, "How often, with God's permission, have small groups defeated the large ones?" God is with those who exercise patience. 249 And when they were facing Goliath and his hordes they prayed: "O Lord, give us endurance and steady our steps, and help us against the deniers of truth." 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 communications of Allah: We recite them to you with truth; and most surely you are (one) of the apostles. 252 ۞ Those messengers - some of them We caused to exceed others. Among them were those to whom Allah spoke, and He raised some of them in degree. And We gave Jesus, the Son of Mary, clear proofs, and We supported him with the Pure Spirit. If Allah had willed, those [generations] succeeding them would not have fought each other after the clear proofs had come to them. But they differed, and some of them believed and some of them disbelieved. And if Allah had willed, they would not have fought each other, but Allah does what He intends. 253
