Quran 28:50 from Surah Al-Qasas on Divine Marvels.
فَإِن لَّمۡ يَسۡتَجِيبُواْ لَكَ فَٱعۡلَمۡ أَنَّمَا يَتَّبِعُونَ أَهۡوَآءَهُمۡۚ وَمَنۡ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيۡرِ هُدٗى مِّنَ ٱللَّهِۚ إِنَّ ٱللَّهَ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ
English translation: But if not they respond to you then know that only they follow their desires And who (is) more astray than (one) who follows his own desire without guidance from Allah Indeed Allah (does) not guide the people the wrongdoers
Transliteration: fa-in lam yastajibu laka fa-i'lam annama yattabi'una ahwaahum waman adallu mimmani ittaba'a hawahu bighayri hudan mina al-lahi inna al-laha la yahdi al-qawma al-zalimina
