An-Nisa 4:154

WarafaAAna fawqahumu attoorabimeethaqihim waqulna lahumu odkhuloo albabasujjadan waqulna lahum la taAAdoo fee assabtiwaakhathna minhum meethaqan ghaleetha

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.

We raised the (Mount of) Tūr high over them for binding them to the pledge, and We said to them, “Do not transgress in (the matter of) the Sabbath.” We took from them a firm pledge.
