And when Saul set out with his forces, he said: "Behold, God will now try you by a river: he who shall drink of it will not belong to me, whereas he who shall refrain from tasting it - he, indeed, will belong to me; but forgiven shall be he who shall scoop up but a single handful." However, save for a few of them, they all drank [their fill] of it. And as soon as he and those who had kept faith with him had crossed the river, the others said: "No strength have we today [to stand up] against Goliath and his forces!" [Yet] those who knew with certainty that they were destined to meet God, replied: "How often has a small host overcome a great host by God's leave! For God is with those who are patient in adversity." 249 And when they were facing Goliath and his hordes they prayed: "O Lord, give us endurance and steady our steps, and help us against the deniers of 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 portents of Allah which We recite unto thee (Muhammad) with truth, and lo! thou art of the number of (Our) messengers; 252 ۞ Of these Messengers (whom We sent for the guidance of mankind), We raised some above the others in rank. Among them was one with whom Allah Himself had direct talks. There were others whom He raised high in rank in other ways. Likewise We gave clear signs to Jesus, son of Mary, and supported him with the Holy Spirit. Had Allah so willed the people who had seen clear signs would not have fought against one another after the Prophets. But (it was not Allah's will to prevent people forcibly from differences: so) they disagreed; then some of them accepted the Truth and others rejected it. If Allah had so willed they would have never fought against one another, but Allah does whatever He pleases (to fulfil His designs. 253
