Surah An-Nisa' (The Women), Verse 155

فَبِمَا نَقْضِهِمْ مِّیْثَاقَهُمْ وَكُفْرِهِمْ بِاٰیٰتِ اللّٰهِ وَقَتْلِهِمُ الْاَنْۢبِیَآءَ بِغَیْرِ حَقٍّ وَّقَوْلِهِمْ قُلُوْبُنَا غُلْفٌ بَلْ طَبَعَ اللّٰهُ عَلَیْهَا بِكُفْرِهِمْ فَلَا یُؤْمِنُوْنَ اِلَّا قَلِیْلًا ۟

Fabimaa naqdihim meesaaqahum wa kufrihim bi Aayaatil laahi wa qatlihimul Ambiyaaa'a bighairi haqqinw wa qawlihim quloobunaa ghulf; bal taba'al laahu 'alaihaa bikufrihim falaa yu'minoona illaa qaleelaa

“(They have incurred divine displeasure): In that they broke their covenant; that they rejected the signs of Allah; that they slew the Messengers in defiance of right; that they said, "Our hearts are the wrappings (which preserve Allah's Word; We need no more)";- Nay, Allah hath set the seal on their hearts for their blasphemy, and little is it they believe;-”
