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 advanced to meet Jalut (Goliath) and his forces, they invoked: "Our Lord! Pour forth on us patience and make us victorious over the disbelieving people." 250 And so by the command of God they defeated them. David killed Goliath, and God gave him kingship and wisdom, and imparted to him the knowledge of whatever He willed. Had it not been for God's repelling some people by means of others, the earth would have been filled with corruption. But God is bountiful to His creatures. 251 These are the signs of God We recite to thee in truth, and assuredly thou art of the number of the Envoys. 252 ۞ Of those messengers, some of whom We have caused to excel others, and of whom there are some unto whom Allah spake, while some of them He exalted (above others) in degree; and We gave Jesus, son of Mary, clear proofs (of Allah's Sovereignty) and We supported him with the holy Spirit. And if Allah had so wiled it, those who followed after them would not have fought one with another after the clear proofs had come unto them. But they differed, some of them believing and some disbelieving. And if Allah had so willed it, they would not have fought one with another; but Allah doeth what He will. 253
