So when Talut left the city along with the armies, he said, “Allah will surely test you with a river; so whoever drinks its water is not mine – and whoever does not drink is mine – except him who takes it in the hollow of his hand”; so they all drank it, except a few of them; thereafter when Talut and the believers with him had crossed the river, they said, “We do not have power this day to face Jalut (Goliath) and his armies”; those who were certain of meeting Allah said, “Many a times has a smaller group overcome a bigger group by Allah’s command; and Allah is with the steadfast.” 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 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.

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
