ذَٰلِكَ بِأَنَّ ٱللَّهَ لَمْ يَكُ مُغَيِّرًا نِّعْمَةً أَنْعَمَهَا عَلَىٰ قَوْمٍ حَتَّىٰ يُغَيِّرُوا مَا بِأَنفُسِهِمْ ۙ وَأَنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌ

Thalika bi-anna Allaha lamyaku mughayyiran niAAmatan anAAamaha AAala qawmin hattayughayyiroo ma bi-anfusihim waanna Allaha sameeAAunAAaleem

That is because Allāh would not change a favor which He had bestowed upon a people until they change what is within themselves. And indeed, Allāh is Hearing and Knowing.
