quran:20:16 –

So do not let one avert you from it who does not believe in it and follows his desire, for you ˹then˺ would perish.  

So do not let him bar you, distract you, from it, that is, from believing in it, who believes not in it but follows his own whim, in denying ˹the truth of˺ it, lest you perish, that is, lest you be ruined if you are barred from ˹remembering˺ it.
القرآن:٢٠:١٦ –

فَلَا يَصُدَّنَّكَ عَنْهَا مَنْ لَا يُؤْمِنُ بِهَا وَاتَّبَعَ هَوَاهُ فَتَرْدَىٰ  

{فلا يَصُدنَّكَ} يصرفنَّك {عنها} أي عن الإيمان بها {من لا يؤمن بها واتبع هواه} في إنكارها {فَتَردى} أي فتهلك إن صددت عنها.
