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 And when they went out against Jalut and his forces they said: Our Lord, pour down upon us patience, and make our steps firm and assist us against the unbelieving people. 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 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 ۞ 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
