And when Saul marched out with his army, he warned: "Allah is going to put you to a test by the side of a river: whoso drinks of its water shall cease to be my companion: he alone shall be~my companion who does not quench his thirst with its water: one may, however, take except a few, drank their fill of it. Afterwards when Saul, and those who had believed with him, crossed the river and advanced forward, the former said to Saul, "We have no power left this day to fight against Goliath and his hosts." But those who believed that one Day they shall meet Allah, declared, "lt has often been that a small host has, by Allah's grace, overcome a big host: for Allah is with those who show fortitude." 249 When they appeared to Goliath and his soldiers, they said: 'Lord, pour upon us patience. Make us firm of foot and give us victory against the nation of unbelievers' 250 So they defeated them by permission of Allah, and David killed Goliath, and Allah gave him the kingship and prophethood and taught him from that which He willed. And if it were not for Allah checking [some] people by means of others, the earth would have been corrupted, but Allah is full of bounty to the worlds. 251 These are the signs of God We recite to thee in truth, and assuredly thou art of the number of the Envoys. 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
