9:77
فَ أَعْقَبَ هُمْ نِفَاقًا فِى قُلُوبِ هِمْ إِلَىٰ يَوْمِ يَلْقَ وْنَ هُۥ بِ مَآ أَخْلَفُ وا۟ ٱللَّهَ مَا وَعَدُ و هُ وَ بِ مَا كَانُ وا۟ يَكْذِبُ ونَ
So He penalized them with hypocrisy in their hearts until the Day they will meet Him - because they failed Allah in what they promised Him and because they [habitually] used to lie.
