Surah 9 : Ayah 77
فَأَعْقَبَهُمْ نِفَاقًا فِى قُلُوبِهِمْ إِلَىٰ يَوْمِ يَلْقَوْنَهُۥ بِمَآ أَخْلَفُوا۟ ٱللَّهَ مَا وَعَدُوهُ وَبِمَا كَانُوا۟ يَكْذِبُونَ
So as a consequence, He caused hypocrisy to take root in their hearts until the Day they meet Him, because of breaking their promise to Allah, and because of their persistent lying.
