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 Advancing towards Goliath and his army, they prayed to God for patience, steadfastness in battle, and for victory over the unbelievers. 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 messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 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
