وَنُقَلِّبُ أَفۡـِٔدَتَهُمۡ وَأَبۡصَٰرَهُمۡ كَمَا لَمۡ يُؤۡمِنُواْ بِهِۦٓ أَوَّلَ مَرَّةٖ وَنَذَرُهُمۡ فِي طُغۡيَٰنِهِمۡ يَعۡمَهُونَ
And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.
۞وَلَوۡ أَنَّنَا نَزَّلۡنَآ إِلَيۡهِمُ ٱلۡمَلَـٰٓئِكَةَ وَكَلَّمَهُمُ ٱلۡمَوۡتَىٰ وَحَشَرۡنَا عَلَيۡهِمۡ كُلَّ شَيۡءٖ قُبُلٗا مَّا كَانُواْ لِيُؤۡمِنُوٓاْ إِلَّآ أَن يَشَآءَ ٱللَّهُ وَلَٰكِنَّ أَكۡثَرَهُمۡ يَجۡهَلُونَ
And even if We had sent down unto them angels, and the dead had spoken unto them, and We had gathered together all things before their very eyes, they would not have believed, unless Allah willed, but most of them behave ignorantly.
وَكَذَٰلِكَ جَعَلۡنَا لِكُلِّ نَبِيٍّ عَدُوّٗا شَيَٰطِينَ ٱلۡإِنسِ وَٱلۡجِنِّ يُوحِي بَعۡضُهُمۡ إِلَىٰ بَعۡضٖ زُخۡرُفَ ٱلۡقَوۡلِ غُرُورٗاۚ وَلَوۡ شَآءَ رَبُّكَ مَا فَعَلُوهُۖ فَذَرۡهُمۡ وَمَا يَفۡتَرُونَ
And so We have appointed for every Prophet enemies - Shayatin (devils) among mankind and jinns, inspiring one another with adorned speech as a delusion (or by way of deception). If your Lord had so willed, they would not have done it, so leave them alone with their fabrications. (Tafseer Qurtubi, Vol. 7, Page 67)
