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 verses of Allah which We recite to you, [O Muhammad], in truth. And indeed, you are from among the messengers. 252 ۞ Some of these apostles have We endowed more highly than others: among them were such as were spoken to by God [Himself,] and some He has raised yet higher.' And We vouchsafed unto Jesus, the son of Mary, all evidence of the truth, and strengthened him with holy inspiration. And if God had so willed, they who succeeded those [apostles] would not have contended with one another after all evidence of the truth had come to them; but [as it was,] they did take to divergent views, and some of them attained to faith, while some of them came to deny the truth. Yet if God had so willed, they would not have contended with one another: but God does whatever He wills. 253
