Quran 24:50 from Surah An-Noor on Divine Marvels.
أَفِي قُلُوبِهِم مَّرَضٌ أَمِ ٱرۡتَابُوٓاْ أَمۡ يَخَافُونَ أَن يَحِيفَ ٱللَّهُ عَلَيۡهِمۡ وَرَسُولُهُۥۚ بَلۡ أُوْلَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ
English translation: Is (there) in their hearts a disease or do they doubt or they fear that Allah will be unjust Allah will be unjust to them and His Messenger Nay those [they] (are) the wrongdoers
Transliteration: afi qulubihim maradun ami ir'tabu am yakhafuna an yahifa al-lahu alayhim warasuluhu bal ulaika humu al-zalimuna
