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 When they advanced to meet Goliath and his forces, they prayed: "Our Lord! Pour out constancy on us and make our steps firm: Help us against those that reject faith." 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 verses of Allah. We recite (them) to you in truth, for you (Prophet Muhammad) are one of the Messengers. 252 ۞ These are the Noble Messengers, to whom We gave excellence over each other; of them are some with whom Allah spoke, and some whom He exalted high above all others; and We gave Eisa (Jesus), the son of Maryam, clear signs and We aided him with the Holy Spirit; and if Allah willed, those after them would not have fought each other after the clear evidences had come to them, but they differed – some remained on faith and some turned disbelievers; and had Allah willed, they would not have fought each other; but Allah may do as He wills. 253
