Quran 29:68 from Surah Al-Ankaboot on Divine Marvels.
وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوۡ كَذَّبَ بِٱلۡحَقِّ لَمَّا جَآءَهُۥٓۚ أَلَيۡسَ فِي جَهَنَّمَ مَثۡوٗى لِّلۡكَٰفِرِينَ
English translation: And who (is) more unjust than (he) who invents against Allah a lie or denies the truth when it has come to him Is there not in Hell an abode for the disbelievers
Transliteration: waman azlamu mimmani if'tara ala al-lahi kadhiban aw kadhaba bil-haqi lamma jaahu alaysa fi jahannama mathwan lil'kafirina
