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 They defeated their enemy through God's will. David slew Goliath and God granted David the kingdom and wisdom and also taught him whatever He wanted. Had God not made one group of people repel the other, the earth would have become full of corruption, but God is generous to His creatures. 251 These are the messages of God. We recite them to you in all truth, as indeed you are one of the apostles. 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
