فَإِن لَّمْ يَسْتَجِيبُوا۟ لَكَ فَٱعْلَمْ أَنَّمَا يَتَّبِعُونَ أَهْوَآءَهُمْ ۚ وَمَنْ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيْرِ هُدًۭى مِّنَ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
And if they answer thee not, then know that what they follow is their lusts. And who goeth farther astray than he who followeth his lust without guidance from Allah. Lo! Allah guideth not wrongdoing folk.
