Surah An-Nisa, ayah 154

4:154

وَرَفَعۡنَا فَوۡقَهُمُ ٱلطُّورَ بِمِيثَٰقِهِمۡ وَقُلۡنَا لَهُمُ ٱدۡخُلُواْ ٱلۡبَابَ سُجَّدٗا وَقُلۡنَا لَهُمۡ لَا تَعۡدُواْ فِي ٱلسَّبۡتِ وَأَخَذۡنَا مِنۡهُم مِّيثَٰقًا غَلِيظٗا ١٥٤

Warafa'nā fawqahumut-tūra bimīthāqihim waqulnā lahumudkhulul-bāba sujjadan waqulnā lahum lā ta'dū fis-sabti wa akhadhnā minhum mīthāqan ghalīzā

And We raised over them the mount for [refusal of] their covenant; and We said to them, "Enter the gate bowing humbly"; and We said to them, "Do not transgress on the sabbath"; and We took from them a solemn covenant.
