Surah At-Tawbah, ayah 77

9:77

فَأَعۡقَبَهُمۡ نِفَاقٗا فِي قُلُوبِهِمۡ إِلَىٰ يَوۡمِ يَلۡقَوۡنَهُۥ بِمَآ أَخۡلَفُواْ ٱللَّهَ مَا وَعَدُوهُ وَبِمَا كَانُواْ يَكۡذِبُونَ ٧٧

Fa a'qabahum nifāqan fī qulūbihim ilā yawmi yalqawnahū bimā akhlafullāha mā wa'adūhu wabimā kānū yakdhibūn

So He penalized them with hypocrisy in their hearts until the Day they will meet Him - because they failed Allāh in what they promised Him and because they [habitually] used to lie.
