Surah An-Nur 24:50

أَفِى قُلُوبِهِم مَّرَضٌ أَمِ ٱرْتَابُوٓا۟ أَمْ يَخَافُونَ أَن يَحِيفَ ٱللَّهُ عَلَيْهِمْ وَرَسُولُهُۥ ۚ بَلْ أُو۟لَـٰٓئِكَ هُمُ ٱلظَّـٰلِمُونَ

Is there disease in their hearts? Or have they doubted? Or do they fear that Allāh will be unjust to them, or His Messenger? Rather, it is they who are the wrongdoers [i.e., the unjust].
