And when Saul marched out with his army, he said: 'Allah will test you with a river. He who drinks from it shall cease to be one of mine but he who does not drink from it, except he who scoops up once with his hand, shall be of mine' But for a few of them, they all drank from it. And when he had crossed it with those who believed, they said: 'We have no power this day against Goliath and his soldiers' But those of them who reckoned they would meet Allah replied: 'Many a small band has, by the permission of Allah, vanquished a mighty army. Allah is with the patient' 249 When they advanced to meet Goliath and his forces, they prayed: "Our Lord! Pour out constancy on us and make our steps firm: Help us against those that reject faith." 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 verses of Allah which We recite to you, [O Muhammad], in truth. And indeed, you are from among the messengers. 252 ۞ We gave some of Our Messengers preference over others. To some of them God spoke and He raised the rank of some others. We gave authoritative proofs to Jesus, son of Mary, and supported him by the Holy Spirit. Had God wanted, the generations who lived after those Messengers would not have fought each other after the authority had come to them. But they differed among themselves, some of them believed in the authority and others denied it. They would not have fought each other had God wanted, but God does as He wills. 253
