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 Allah We rehearse them unto thee with truth, and verily thou art of the sent ones. 252 ۞ And those Messengers, some We have preferred above others; some there are to whom God spoke, and some He raised in rank. And We gave Jesus son of Mary the clear signs, and confirmed him with the Holy Spirit. And had God willed, those who came after him would not have fought one against the other after the clear signs had come to them; but they fell into variance, and some of them believed, and some disbelieved; and had God willed they would not have fought one against the other; but God does whatsoever He desires. 253
