وَرَفَعْنَا فَوْقَهُمُ ٱلطُّورَ بِمِيثَٰقِهِمْ وَقُلْنَا لَهُمُ ٱدْخُلُوا۟ ٱلْبَابَ سُجَّدًۭا وَقُلْنَا لَهُمْ لَا تَعْدُوا۟ فِى ٱلسَّبْتِ وَأَخَذْنَا مِنْهُم مِّيثَٰقًا غَلِيظًۭا
And We caused the Mount to tower above them at (the taking of) their covenant: and We bade them: Enter the gate, prostrate! and We bode them: Transgress not the Sabbath! and We took from them a firm covenant.
