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 Advancing towards Goliath and his army, they prayed to God for patience, steadfastness in battle, and for victory over the unbelievers. 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 portents of Allah which We recite unto thee (Muhammad) with truth, and lo! thou art of the number of (Our) messengers; 252 ۞ We have made some of these apostles to excel the others among them are they to whom Allah spoke, and some of them He exalted by (many degrees of) rank; and We gave clear miracles to Isa son of Marium, and strengthened him with the holy spirit. And if Allah had pleased, those after them would not have fought one with another after clear arguments had come to them, but they disagreed; so there were some of them who believed and others who denied; and if Allah had pleased they would not have fought one with another, but Allah brings about what He intends. 253
