So they put them to flight by Allah's permission. And Dawood slew Jalut, and Allah gave him kingdom and wisdom, and taught him of what He pleased. And were it not for Allah's repelling some men with others, the earth would certainly be in a state of disorder; but Allah is Gracious to the creatures.

And even if there were a Quran with which the mountains were made to pass away, or the earth were travelled over with it, or the dead were made to speak thereby; nay! the commandment is wholly Allah's, Have not yet those who believe known that if Allah please He would certainly guide all the people? And (as for) those who disbelieve, there will not cease to afflict them because of what they do a repelling calamity, or it will alight close by their abodes, until the promise of Allah comes about; surely Allah will not fail in (His) promise.
