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 By Allah's will they routed them; and David slew Goliath; and Allah gave him power and wisdom and taught him whatever (else) He willed. And did not Allah Check one set of people by means of another, the earth would indeed be full of mischief: But Allah is full of bounty to all the worlds. 251 These are the messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 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
