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 By Allah's will they routed them; and David slew Goliath; and Allah gave him power and wisdom and taught him whatever (else) He willed. And did not Allah Check one set of people by means of another, the earth would indeed be full of mischief: But Allah is full of bounty to all the worlds. 251 These are the Signs of Allah: we rehearse them to thee in truth: verily Thou art one of the 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
