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 they routed them, by the leave of God, and David slew Goliath; and God gave him the kingship, and Wisdom, and He taught him such as He willed. Had God not driven back the people, some by the means of others, the earth had surely corrupted; but God is bounteous unto all beings. 251 (Muhammad), these are the revelations which We recite to you for a genuine purpose. Certainly you are one of Our Messengers. 252 ۞ Of these Messengers, We have preferred some above others. To some Allah spoke; and some He raised in rank. We gave (Prophet) Jesus, the son of Mary, clear signs and strengthened him with the Spirit of Purity (Gabriel). Had Allah willed, those who succeeded them would not have fought against one another after the clear verses came to them. But they differed among themselves; some believed, and others disbelieved. Yet had Allah willed, they would not have fought against one another. Allah does whatever He will. 253
