An Nisa, 155 Ayah
4:155
فَبِمَا نَقۡضِهِم مِّيثَٰقَهُمۡ وَكُفۡرِهِم بِـَٔايَٰتِ ٱللَّهِ وَقَتۡلِهِمُ ٱلۡأَنۢبِيَآءَ بِغَيۡرِ حَقّٖ وَقَوۡلِهِمۡ قُلُوبُنَا غُلۡفُۢۚ بَلۡ طَبَعَ ٱللَّهُ عَلَيۡهَا بِكُفۡرِهِمۡ فَلَا يُؤۡمِنُونَ إِلَّا قَلِيلٗا ١٥٥
Fabimā Naqđihim Mīthāqahum Wa Kufrihim Bi'āyāti Al-Lahi Wa Qatlihimu Al-'Anbiyā'a Bighayri Ĥaqqin Wa Qawlihim Qulūbunā Ghulfun ۚ Bal Ţaba`a Al-Lahu `Alayhā Bikufrihim Falā Yu'uminūna 'Illā Qalīlāan
And [We cursed them] for their breaking of the covenant and their disbelief in the signs of Allah and their killing of the prophets without right and their saying, "Our hearts are wrapped". Rather, Allah has sealed them because of their disbelief, so they believe not, except for a few.
