Have these disbelievers who do not believe in the Hereafter then not seen the greatness of Allah's power in what is between their hands and what is behind them of the heaven and the earth from what dazzles the intellects, and that they both had surely encompassed them? if We willed We would sink with them the earth, as We performed with Qarun, or We would send down upon them fragments from the punishment, as We performed with the people of Shu'ayb, for the sky had surely rained upon them fire thus it burned them. Indeed in that which We mentioned of Our power is surely a manifest indication for every servant returning to his Lord with repentance, and an acknowledger for Him with His uniqueness, and a sincere one for Him in the worship.
