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 revelations of God which We recite to you in all truth, for you are truly one of the messengers. 252 ۞ Of these Messengers, We have preferred some above others. To some Allah spoke; and some He raised in rank. We gave (Prophet) Jesus, the son of Mary, clear signs and strengthened him with the Spirit of Purity (Gabriel). Had Allah willed, those who succeeded them would not have fought against one another after the clear verses came to them. But they differed among themselves; some believed, and others disbelieved. Yet had Allah willed, they would not have fought against one another. Allah does whatever He will. 253
