The Mountain - 52:1 And to Tur,
In the context of verses 1, 2, 3: "The Torah, the book given to the Prophet Moses on Mount Tur, part of which he revealed to the Children of Israel and part of which he concealed, was recorded and published on parchment."
The Cow/2:93 "Remember when We raised Mount Tur over you and took a promise from you: "Hold fast to what I command you and listen."But they said: "We listened and disobeyed". Because of their disbelief, their hearts were deceived by the calf. Say: "If you have believed, how badly your faith is guiding you!"

The Cattle/6:91 "They did not appreciate Allah properly when they said: "Allah does not send down anything to any man". Say: "Who sent down the Book which Moses brought as a guidance and light for the people, which you wrote on paper to show them, but you concealed most of it. Through it you have learned what you and your fathers did not know?"Say: "Allah"and leave them in the error into which they have plunged, and let them play."

The Heights/7:145 "We wrote on tablets for Moses a detailed explanation of all things and an admonition: "Hold fast to this teaching, and tell your people to hold fast to it in the best way. I will show you the final destination of the wayward."
The Heights/7:154 When Moses´ nerves calmed down, he took the tablets. On them was written guidance and mercy for those who honor their Lord.
