Surah Al-Qasas Verse 50 - English Translation by A. J. Arberry
Surah Al-Qasasفَإِن لَّمۡ يَسۡتَجِيبُواْ لَكَ فَٱعۡلَمۡ أَنَّمَا يَتَّبِعُونَ أَهۡوَآءَهُمۡۚ وَمَنۡ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيۡرِ هُدٗى مِّنَ ٱللَّهِۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّـٰلِمِينَ
Then if they do not answer thee, know that they are only following their caprices; and who is further astray than he who follows his caprice without guidance from God? Surely God guides not the people of the evildoers
