Quran 15:19 — Al-Hijr Valley (Al-Hijr)

As for the earth, we constructed it, and placed on it stabilizers (mountains), and we grew on it a perfect balance of everything.

[15:18] If any of them sneaks around to listen, a mighty projectile will chase him back.

[15:20] We made it habitable for you,* and for creatures you do not provide for.
