So is one who [stands] upon a clear evidence from his Lord [like the aforementioned]? And a witness from Him follows it, and before it was the Scripture of Moses to lead and as mercy. Those [believers in the former revelations] believe in the Quran. But whoever disbelieves in it from the [various] factions – the Fire is his promised destination. So be not in doubt about it. Indeed, it is the truth from your Lord, but most of the people do not believe.
(Surah Hud 17 Quran)
