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 arrayed themselves against Jalut and his hosts, they said: our Lord pour forth on us patience, and set firm our feet, and make us triumph over the infidel people. 250 And they routed them, by the leave of God, and David slew Goliath; and God gave him the kingship, and Wisdom, and He taught him such as He willed. Had God not driven back the people, some by the means of others, the earth had surely corrupted; but God is bounteous unto all beings. 251 These are the messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 252 ۞ We gave some of Our Messengers preference over others. To some of them God spoke and He raised the rank of some others. We gave authoritative proofs to Jesus, son of Mary, and supported him by the Holy Spirit. Had God wanted, the generations who lived after those Messengers would not have fought each other after the authority had come to them. But they differed among themselves, some of them believed in the authority and others denied it. They would not have fought each other had God wanted, but God does as He wills. 253
