﴿ وَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ كَذَّبَ بِٱلْحَقِّ لَمَّا جَآءَهُۥٓ ۚ أَلَيْسَ فِى جَهَنَّمَ مَثْوًۭى لِّلْكَٰفِرِينَ ﴾

“And who could be more wicked than he who attributes his own lying inventions to God, or gives the lie to the truth when it comes unto him [through revelation]? Is not hell the [proper] abode for all who [thus] deny the truth?”
