Quran 4:154 from Surah An-Nisaa on Divine Marvels.
وَرَفَعۡنَا فَوۡقَهُمُ ٱلطُّورَ بِمِيثَٰقِهِمۡ وَقُلۡنَا لَهُمُ ٱدۡخُلُواْ ٱلۡبَابَ سُجَّدٗا وَقُلۡنَا لَهُمۡ لَا تَعۡدُواْ فِي ٱلسَّبۡتِ وَأَخَذۡنَا مِنۡهُم مِّيثَٰقًا غَلِيظٗا
English translation: And We raised over them the mount for their covenant and We said to them Enter the gate prostrating And We said to them (Do) not transgress in the Sabbath And We took from them a covenant solemn
