And We have set on the earth mountains standing firm lest it should shake with them and We have made therein broad highways (between mountains) for them to pass through: that they may receive guidance. [Qur’an 21:31, Translated A.Yusuf Ali]
Have We not made the earth as a wide expanse, and the mountains as pegs? [Qur’an 78:6-7, Translated A.Yusuf Ali]
