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 Accordingly, when they marched forward to fight with Goliath and his hosts, they prayed, "Our Lord, bless us with fortitude, make firm our foothold and give us victory over the unbelieving host." 250 Then they vanquished them by the leave of Allah, and Da'ud slew Jalut, and Allah vouchsafed him dominion, and wisdom and taught him of that which He willed. And, if not for Allah's repelling people, some of them by means of others, the earth surely were corrupted; but Allah is Gracious unto the worlds. 251 These are Allah's revelations, which We are conveying to you accurately. And O Muhammad, most surely you are of those who have been sent as Messengers. 252 ۞ Of these messengers, We have given something additional among them. There are some to whom God spoke directly and others He exalted in rank. We gave Jesus, son of Mary clear signs, and strengthened him with the holy spirit. Had God pleased, those who succeeded them would not have fought against one another after the clear signs had come to them. But they disagreed among themselves; some believed, while others did not. Yet had God willed, they would not have fought against one another; but God does whatever He wills. 253
