الانبياۤء — Al-Anbiya' Ayat 31
وَجَعَلْنَا فِى الْاَرْضِ رَوَاسِيَ اَنْ تَمِيْدَ بِهِمْۖ وَجَعَلْنَا فِيْهَا فِجَاجًا سُبُلًا لَّعَلَّهُمْ يَهْتَدُوْنَ
Wa ja‘alnā fil-arḍi rawāsiya an tamīda bihim, wa ja‘anā fīhā fijājan subulal la‘allahum yahtadūn(a).
"And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided."
