The use of this term...

The use of this term, for the earth, is full of meaning because, on the one hand, most parts of the land are so smooth and level that man can build houses thereon and prepares gardens and farms thereabout. On the other hand, all his necessities are found over the Earth or hidden on its insides in the form of raw materials and valuable mines.

And, then again, the earth swallows up man's refuse, and the corpse of the dead are burned in it; (because of their dissolution and the absorption of their various microbes in the soil) , to be vanished by the wonderful properties of dust. Furthermore, the Earth, itself, rotates and then rotates around the Sun by which the days and nights and the four seasons of the year appear and these, too, play an important role in Man's life.

In addition, the earth stores up, under its surface, much of the water that falls down from heaven nd then, gradually, distributes it through springs and subterranean canals. In short, everything useful for the comfort of the creatures living on the land, is supplied on this smooth bed; the Earth. The importance of this great blessing will be made clear only when some slight changes happen to it.

Then, in order that the importance of the mountains may not be forgotten, in contrast to the smoothness of the surface of the Earth, it says: And the mountains as pegs?. Mountains have deep and expanding formations joined together under the ground. They, armor-like, protect the Earth's surface against the inner pressure caused by the central molten lava, and the outer pressure resulting from the moon.

Also, mountains stand as lofty walls in the way of terrible storms, and as safe abodes for men to rest, therein. If they were not so, Man's life would be quite uncomfortable under the constant strikes of violent storms. In addition, mountains are the source of sweet water as well as different precious mines. Adding, still, to all of the above, the mountains' peaks; like gears of a wheel, restrain, by friction, the thick air mass around the globe, as if dragging it along with themselves.

Some scientists say that if the surface of the Earth were a flat plain, then, when the globe turns, the air would slide over it and great storms would develop. This constant turmoil would make the surface too hot and uninhabitable. After mentioning these two phenomenal blessings of Allah, it refers to the spiritual signs of Allah and says: And we created you in pairs.
