Surah Al-Qasas, ayah 50

28:50

فَإِن لَّمۡ يَسۡتَجِيبُواْ لَكَ فَٱعۡلَمۡ أَنَّمَا يَتَّبِعُونَ أَهۡوَآءَهُمۡۚ وَمَنۡ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيۡرِ هُدٗى مِّنَ ٱللَّهِۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ ٥٠

Fa il lam yastajībū laka fa'lam annamā yattabi'ūna ahwā'ahum waman adallu mimmanit-taba'a hawāhu bighayri hudam minallāhi innallāha lā yahdil-qawmaz-zālimīn

But if they do not respond to you - then know that they only follow their [own] desires. And who is more astray than one who follows his desire without guidance from Allāh? Indeed, Allāh does not guide the wrongdoing people.
