And when Saul set out with his forces, he said: "Behold, God will now try you by a river: he who shall drink of it will not belong to me, whereas he who shall refrain from tasting it - he, indeed, will belong to me; but forgiven shall be he who shall scoop up but a single handful." However, save for a few of them, they all drank [their fill] of it. And as soon as he and those who had kept faith with him had crossed the river, the others said: "No strength have we today [to stand up] against Goliath and his forces!" [Yet] those who knew with certainty that they were destined to meet God, replied: "How often has a small host overcome a great host by God's leave! For God is with those who are patient in adversity." 249 Accordingly, when they marched forward to fight with Goliath and his hosts, they prayed, "Our Lord, bless us with fortitude, make firm our foothold and give us victory over the unbelieving host." 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 portents of Allah which We recite unto thee (Muhammad) with truth, and lo! thou art of the number of (Our) messengers; 252 ۞ Those Messengers! We preferred some to others; to some of them Allah spoke (directly); others He raised to degrees (of honour); and to 'Iesa (Jesus), the son of Maryam (Mary), We gave clear proofs and evidences, and supported him with Ruh-ul-Qudus [Jibrael (Gabriel)]. If Allah had willed, succeeding generations would not have fought against each other, after clear Verses of Allah had come to them, but they differed - some of them believed and others disbelieved. If Allah had willed, they would not have fought against one another, but Allah does what He likes. 253
