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 And when they came face to face with Goliath and his forces, they prayed: "O our Sustainer! Shower us with patience in adversity, and make firm our steps, and succour us against the people who deny the truth!" 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 revelations of Allah We rehearse them unto thee with truth, and verily thou art of the sent ones. 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
