When Saul led his armies, he said: "God will test you by a stream. Whoever drinks its water will not be of me; but those who do not drink shall be on my side. The only exception will be those who scoop up a palmful of water with their hands." And but for a few they all drank of its water. When they had crossed it, and those who believed with him, they said: "We have no strength to combat Goliath and his forces today. But those who believed they have to face their Lord, said: "Many a time has a small band defeated a large horde by the will of God. God is with those who are patient (and persevere)." 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 verses of Allah. We recite (them) to you in truth, for you (Prophet Muhammad) are one of the Messengers. 252 ۞ We gave some of Our Messengers preference over others. To some of them God spoke and He raised the rank of some others. We gave authoritative proofs to Jesus, son of Mary, and supported him by the Holy Spirit. Had God wanted, the generations who lived after those Messengers would not have fought each other after the authority had come to them. But they differed among themselves, some of them believed in the authority and others denied it. They would not have fought each other had God wanted, but God does as He wills. 253
