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 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 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
