Surah At-Taubah (The Repentance), Verse 77

فَاَعْقَبَهُمْ نِفَاقًا فِیْ قُلُوْبِهِمْ اِلٰی یَوْمِ یَلْقَوْنَهٗ بِمَاۤ اَخْلَفُوا اللّٰهَ مَا وَعَدُوْهُ وَبِمَا كَانُوْا یَكْذِبُوْنَ ۟

Fa a'qabahum nifaaqan fee quloobihim ilaa Yawmi yalqaw nahoo bimaaa akhlaful laaha maa wa'adoohu wa bimaa kaanoo yakhziboon

“So He hath put as a consequence hypocrisy into their hearts, (to last) till the Day, whereon they shall meet Him: because they broke their covenant with Allah, and because they lied (again and again).”
