وَأَلْقَىٰ فِي الْأَرْضِ رَوَاسِيَ أَن تَمِيدَ بِكُمْ وَأَنْهَارًا وَسُبُلًا لَّعَلَّكُمْ تَهْتَدُونَ ١٥

And He is the One Who has created firm mountains in the earth (by allying various elements) lest it tremor whilst carrying you (revolving in its orbit), and rivers and (also natural) routes so that you may find way (to reach the destinations), (16:15)
