When Saul set forth with the army he said, "God will test you with a river. Those who drink its water will not be of my people and those who do not even taste the water or who only taste some of it from within the hollow of their hand, will be my friends. They all drank the water except a few of them. When Saul and those who believed in him crossed the river, his people said, "We do not have the strength to fight against Goliath and his army." Those who thought that they would meet God said, "How often, with God's permission, have small groups defeated the large ones?" God is with those who exercise patience. 249 So, when they went forth against Goliath and his hosts, they said, 'Our Lord, pour out upon us patience, and make firm our feet, and give us aid against the people of the unbelievers!' 250 By the will of God they defeated them, and David killed Goliath, and God gave him kingship and wisdom, and taught him whatsoever He pleased. If God did not make men deter one another this earth would indeed be depraved. But gracious is God to the people of the world. 251 These are the communications of Allah: We recite them to you with truth; and most surely you are (one) of the apostles. 252 ۞ Those Messengers! We preferred some to others; to some of them Allah spoke (directly); others He raised to degrees (of honour); and to 'Iesa (Jesus), the son of Maryam (Mary), We gave clear proofs and evidences, and supported him with Ruh-ul-Qudus [Jibrael (Gabriel)]. If Allah had willed, succeeding generations would not have fought against each other, after clear Verses of Allah had come to them, but they differed - some of them believed and others disbelieved. If Allah had willed, they would not have fought against one another, but Allah does what He likes. 253
