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 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 (Muhammad), these are the revelations which We recite to you for a genuine purpose. Certainly you are one of Our Messengers. 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
