وَأَلْقَى فِي الأَرْضِ رَوَاسِيَ أَن تَمِيدَ بِكُمْ وَأَنْهَارًا وَسُبُلاً لَّعَلَّكُمْ تَهْتَدُونَ
[16:15]
And He has cast great mountains in the earth lest it might be convulsed with you, and rivers and roads that you may go aright,
And He has set up on the earth mountains standing firm, lest it should shake with you; and rivers and roads; that ye may guide yourselves;
And He hath cast into the earth firm hills that it quake not with you, and streams and roads that ye may find a way.
