Even if there were a Quran, by which mountains could be set in motion, or by which the earth could be shattered, or by which the dead could be made to speak. In fact, every decision rests with God. Did the believers not give up and realize that had God willed, He would have guided all humanity? Disasters will continue to strike those who disbelieve, because of their deeds, or they fall near their homes, until God’s promise comes true. God never breaks a promise.
