ذَٰلِكَ بِأَنَّ ٱللَّهَ لَمْ يَكُ مُغَيِّرًۭا نِّعْمَةً أَنْعَمَهَا عَلَىٰ قَوْمٍ حَتَّىٰ يُغَيِّرُوا۟ مَا بِأَنفُسِهِمْ ۙ وَأَنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌۭ
That is because Allah never changeth the grace He hath bestowed on any people until they first change that which is in their hearts, and (that is) because Allah is Hearer, Knower.
Surah Al-Anfaal(8:53)
