4:155
فَبِمَا نَقْضِهِم مِّيثَـٰقَهُمْ وَكُفْرِهِم بِـَٔايَـٰتِ ٱللَّهِ وَقَتْلِهِمُ ٱلْأَنۢبِيَآءَ بِغَيْرِ حَقٍّ وَقَوْلِهِمْ قُلُوبُنَا غُلْفٌۢ ۚ بَلْ طَبَعَ ٱللَّهُ عَلَيْهَا بِكُفْرِهِمْ فَلَا يُؤْمِنُونَ إِلَّا قَلِيلًا١٥٥
And [We cursed them]1 for their breaking of the covenant and their disbelief in the signs of Allāh and their killing of the prophets without right and their saying, "Our hearts are wrapped" [i.e., sealed against reception]. Rather, Allāh has sealed them because of their disbelief, so they believe not, except for a few.2
