فإن لم يستجيبوا لك فاعلم أنما يتبعون أهواءهم ومن أضل ممن اتبع (28:50) بالانجليزي

﴿فَإِن لَّمْ يَسْتَجِيبُوا لَكَ فَاعْلَمْ أَنَّمَا يَتَّبِعُونَ أَهْوَاءَهُمْ ۚ وَمَنْ أَضَلُّ مِمَّنِ اتَّبَعَ هَوَاهُ بِغَيْرِ هُدًى مِّنَ اللَّهِ ۚ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ﴾
[ القصص: 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.

عبد الله يوسف علي

But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing.

تقي الدين الهلالي

But if they answer you not (i.e. do not believe in your doctrine of Islamic Monotheism, nor follow you), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily! Allah guides not the people who are Zalimun (wrong-doers, disobedient to Allah, and polytheists).

صفي الرحمن المباركفوري

But if they answer you not, then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah Verily, Allah guides not the people who are wrongdoers.
