So when Talut left the city along with the armies, he said, “Allah will surely test you with a river; so whoever drinks its water is not mine – and whoever does not drink is mine – except him who takes it in the hollow of his hand”; so they all drank it, except a few of them; thereafter when Talut and the believers with him had crossed the river, they said, “We do not have power this day to face Jalut (Goliath) and his armies”; those who were certain of meeting Allah said, “Many a times has a smaller group overcome a bigger group by Allah’s command; and Allah is with the steadfast.” 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 ۞ Of those messengers, some of whom We have caused to excel others, and of whom there are some unto whom Allah spake, while some of them He exalted (above others) in degree; and We gave Jesus, son of Mary, clear proofs (of Allah's Sovereignty) and We supported him with the holy Spirit. And if Allah had so wiled it, those who followed after them would not have fought one with another after the clear proofs had come unto them. But they differed, some of them believing and some disbelieving. And if Allah had so willed it, they would not have fought one with another; but Allah doeth what He will. 253
