Following desires versus divine guidance

فَإِن لَّمْ يَسْتَجِيبُوا۟ لَكَ فَٱعْلَمْ أَنَّمَا يَتَّبِعُونَ أَهْوَآءَهُمْ ۚ وَمَنْ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيْرِ هُدًى مِّنَ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ

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.

إِنْ هِىَ إِلَّآ أَسْمَآءٌ سَمَّيْتُمُوهَآ أَنتُمْ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلْطَـٰنٍ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَمَا تَهْوَى ٱلْأَنفُسُ ۖ وَلَقَدْ جَآءَهُم مِّن رَّبِّهِمُ ٱلْهُدَىٰٓ

They are not but [mere] names you have named them - you and your forefathers - for which Allāh has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance.
