فَاِنْ لَّمْ يَسْتَجِيْبُوْا لَكَ فَاعْلَمْ اَنَّمَا يَتَّبِعُوْنَ اَهْوَاۤءَهُمْۗ وَمَنْ اَضَلُّ مِمَّنِ اتَّبَعَ هَوٰىهُ بِغَيْرِ هُدًى مِّنَ اللّٰهِ ۗاِنَّ اللّٰهَ لَا يَهْدِى الْقَوْمَ الظّٰلِمِيْنَ ࣖ ( القصص: ٥٠ )
Fa il lam yastajeeboo laka fa'lam annamaa yattabi'oona ahwaaa'ahum; w aman adallu mimmanit taba'a hawaahu bighari hudam minal laah; innal laaha laa yahdil qawmaz zaalimeen (al-Q̈aṣaṣ 28:50)
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 Allah? Indeed, Allah does not guide the wrongdoing people. (Al-Qasas  : 50)

So if they do not respond to you, be sure that they are only following their desires. And who is more astray than the one who follows his desire without guidance from Allah. Surely Allah does not take the wrongdoing people onto the right path.
