Quran 16:15 — The Bee (Al-Nahl)

And He placed stabilizers (mountains) on earth, lest it tumbles with you, as well as rivers and roads, that you may be guided.

[16:14] And He committed the sea to serve you; you eat from it tender meat, and extract jewelry which you wear. And you see the ships roaming it for your commercial benefits, as you seek His bounties, that you may be appreciative.

[16:16] And landmarks, as well as the stars; to be used for navigation.
