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 So they defeated them by permission of Allah, and David killed Goliath, and Allah gave him the kingship and prophethood and taught him from that which He willed. And if it were not for Allah checking [some] people by means of others, the earth would have been corrupted, but Allah is full of bounty to the worlds. 251 These are the revelations of Allah We rehearse them unto thee with truth, and verily thou art of the sent ones. 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
