Quran 6:21 from Surah Al-An'aam on Divine Marvels.
وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوۡ كَذَّبَ بِـَٔايَٰتِهِۦٓۚ إِنَّهُۥ لَا يُفۡلِحُ ٱلظَّٰلِمُونَ
English translation: And who (is) more unjust than (he) who invents against Allah a lie or rejects His Signs Indeed not will be successful the wrongdoers
Transliteration: waman azlamu mimmani if'tara ala al-lahi kadhiban aw kadhaba biayatihi innahu la yuf'lihu al-zalimuna
