Some of the wonderful signs of creation is pointed to here:ِ

      ``We spread out the earth and set the immovables in it.''

      In this verse the earth is said to have been spread out perhaps, like a carpet. This probably alludes to its coming out of the waters gradually:ِ

      ``We set in the earth firm mountains, and produced in it of everything well proportioned (WELL MEASURED).''

      The Arabic, RAVÄSI literally means immovable, the other shades of which are firmly fixed, stationary, steadfast, and all these shades of meanings are the qualifications of the mountains, that are set or planted in the earth to keep it steady against viberations. Our globe has various motions like its revolution in the orbit around the sun, or its rotation on its axis, and its movement with the solar system through the space. Therefore, the mountains which are heavy and fixed firmly in the earth act as weights and nails to keep everything steady. They resist interviberations of the earth, and stand firm against powerful winds and storms.
