And when we see that the Qur’an considers the creation of man out of /tin/ (mud), it is because this substance is a mixture of water and dust. This subject is also noteworthy that the main part of man’s body, as well as that of many animals, mostly consists of water, (about seventy percent). Some have objected that the creation of the angels and jinn both is certainly not from water, though they are some living creatures.
The answer of it is clear, because the purpose in this context is those living creatures which are tangible for us. An Islamic tradition indicates that once a person asked Imam Sadiq (as) about the taste of water. The Imam (as) at first said: “Ask with the aim that you learn something, not with the purpose of seeking pretext.” Then he (as) added: “The taste of water is the taste of life.
Allah, Be He Glorified, has said: ‘And We made from water every living thing’.” [^4] In the summer, in particular, when a person, tolerating continued thirst, reaches some wholesome water in that hot weather, after drinking the first gulps of it, he feels that a spirit of life is blown into his body. The Imam, in fact intends to clarify the relation and dependence of life and water by this beautiful expression.
It says: “And We set in the earth firm mountains lest it should shake with them (people)…” As a shield, mountains have embraced the earth, and this causes that they prevent the intensive shakes of the earth on a large scale which appear as a result of the pressure of the inner gases of it. Moreover, this very arrangement of the mountains usually decreases the movements of the crust of the earth against the low tides and high tides of the moon to the least.
On the other hand, if there were not any mountains, the surface of the earth would not have any peace because of the hurricanes, as it is seen in the dry hot deserts as well as salt deserts. Mountains are good places for preserving snow to store water in them for the summer. They are often good and appropriate environments for the growth of plants and animals.
