فَأَعْقَبَهُمْ نِفَاقًا فِي قُلُوبِهِمْ إِلَىٰ يَوْمِ يَلْقَوْنَهُ بِمَا أَخْلَفُوا اللَّهَ مَا وَعَدُوهُ وَبِمَا كَانُوا يَكْذِبُونَ (77)
(9:77) As a consequence of the breach of the covenant they had made with Allah and the lies they told, He set hypocrisy deep in their hearts that will follow them till the Day when they shall meet Him.
