free will and divine decree

وَنُقَلِّبُ أَفْـِٔدَتَهُمْ وَأَبْصَـٰرَهُمْ كَمَا لَمْ يُؤْمِنُوا۟ بِهِۦٓ أَوَّلَ مَرَّةٍ وَنَذَرُهُمْ فِى طُغْيَـٰنِهِمْ يَعْمَهُونَ

And We will turn away their hearts and their eyes just as they refused to believe in it [i.e., the revelation] the first time. And We will leave them in their transgression, wandering blindly.

تِلْكَ ٱلْقُرَىٰ نَقُصُّ عَلَيْكَ مِنْ أَنۢبَآئِهَا ۚ وَلَقَدْ جَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَـٰتِ فَمَا كَانُوا۟ لِيُؤْمِنُوا۟ بِمَا كَذَّبُوا۟ مِن قَبْلُ ۚ كَذَٰلِكَ يَطْبَعُ ٱللَّهُ عَلَىٰ قُلُوبِ ٱلْكَـٰفِرِينَ

Those cities - We relate to you, [O Muḥammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allāh seal over the hearts of the disbelievers.

يَوْمَ تُوَلُّونَ مُدْبِرِينَ مَا لَكُم مِّنَ ٱللَّهِ مِنْ عَاصِمٍ ۗ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ

The Day you will turn your backs fleeing; there is not for you from Allāh any protector. And whoever Allāh sends astray - there is not for him any guide.
