And when Saul set out with the army, he said: Lo! Allah will try you by (the ordeal of) a river. Whosoever therefore drinketh thereof he is not of me, and whosoever tasteth it not he is of me, save him who taketh (thereof) in the hollow of his hand. But they drank thereof, all save a few of them. And after he had crossed (the river), he and those who believed with him, they said: We have no power this day against Goliath and his hosts. But those who knew that they would meet Allah exclaimed: How many a little company hath overcome a mighty host by Allah's leave! Allah is with the steadfast. 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 They defeated their enemy through God's will. David slew Goliath and God granted David the kingdom and wisdom and also taught him whatever He wanted. Had God not made one group of people repel the other, the earth would have become full of corruption, but God is generous to His creatures. 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 ۞ 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
