And if there was a Quran with which mountains were moved, or the earth was split open, or the dead were to speak, (this Quran would be that Book!) but, truly, the command for all things is with Allah! Do the believers not know, that if Allah willed, He could have guided all mankind (to the Right)? But for the disbelievers— Disaster will never stop to grab them for their (ill) deeds, or fall close to their homes, until the promise of Allah has come true, because truly, Allah will not fail in His promise.
