بِئْسَمَا ٱشْتَرَوْا۟ بِهِۦٓ أَنفُسَهُمْ أَن يَكْفُرُوا۟ بِمَآ أَنزَلَ ٱللَّهُ بَغْيًا أَن يُنَزِّلَ ٱللَّهُ مِن فَضْلِهِۦ عَلَىٰ مَن يَشَآءُ مِنْ عِبَادِهِۦ ۖ فَبَآءُو بِغَضَبٍ عَلَىٰ غَضَبٍۢ ۚ وَلِلْكَٰفِرِينَ عَذَابٌۭ مُّهِينٌۭ
Evil is that for which they sell their souls: that they should disbelieve in that which Allah hath revealed, grudging that Allah should reveal of His bounty unto whom He will of His slaves. They have incurred anger upon anger. For disbelievers is a shameful doom.
