Surat An-Nisaa (The Women) - النساء

وَرَفَعْنَا فَوْقَهُمُ ٱلطُّورَ بِمِيثَٰقِهِمْ وَقُلْنَا لَهُمُ ٱدْخُلُوا۟ ٱلْبَابَ سُجَّدًا وَقُلْنَا لَهُمْ لَا تَعْدُوا۟ فِى ٱلسَّبْتِ وَأَخَذْنَا مِنْهُم مِّيثَٰقًا غَلِيظًا ﴿١٥٤﴾ فَبِمَا نَقْضِهِم مِّيثَٰقَهُمْ وَكُفْرِهِم بِـَٔايَٰتِ ٱللَّهِ وَقَتْلِهِمُ ٱلْأَنۢبِيَآءَ بِغَيْرِ حَقٍّ وَقَوْلِهِمْ قُلُوبُنَا غُلْفٌۢ بَلْ طَبَعَ ٱللَّهُ عَلَيْهَا بِكُفْرِهِمْ فَلَا يُؤْمِنُونَ إِلَّا قَلِيلًا﴿١٥٥﴾

And We lifted the mountain (Sainai) over them at (the taking of the covenant) and We said to them: Enter the door making obeisance; and We said to them: Do not exceed the limits of the Sabbath, and We made with them a firm covenant. Therefore, for their breaking their covenant and their disbelief in the communications of Allah and their killing the prophets wrongfully and their saying: Our hearts are covered; nay! Allah set a seal upon them owing to their unbelief, so they shall not believe except a few.
