وَجَعَلْنَا فِي الْأَرْضِ رَوَاسِيَ أَن تَمِيدَ بِهِمْ وَجَعَلْنَا فِيهَا فِجَاجًا سُبُلًا لَّعَلَّهُمْ يَهْتَدُونَ (31)
(21:31) And We set mountains firmly in the earth lest it should tilt to one side along with them *30 , and We left therein open paths *31 so that they may find their way. *32
*30) For explanation, see E. N. 12 of An-Nahl (XVI).
*31) "Open paths" are the passes between high mountains and the valleys and ravines made by the rivers in the mountainous regions and other natural ways that connect different regions on the earth.
*32) This is a very meaningful sentence. It may mean that the people may find paths for travelling on the earth, and it may also mean that the wisdom that underlies the skill and the system of their creation may guide them to the Reality.
