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 met Goliath and his warriors, they said, "Our Lord, bestow patience upon us, make us stand firm, and help us against those who deny the truth." 250 They defeated their enemy through God's will. David slew Goliath and God granted David the kingdom and wisdom and also taught him whatever He wanted. Had God not made one group of people repel the other, the earth would have become full of corruption, but God is generous to His creatures. 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 ۞ Of all these apostles We have favoured some over the others. God has addressed some of them, and the stations of some have been exalted over the others. And to Jesus, son of Mary, We gave tokens, and reinforced him with divine grace. If God had so willed those who came after them would never have contended when clear signs had come to them. But dissensions arose, some believed, some denied. And if God had willed they would never have fought among themselves. But God does whatsoever He please. 253
