LOOK AT CAMEL AS IT IS A SIGN!
VERSES NO.17-26
The key requisite for attainment to the heavenly blessings is to know God. For knowing Him, four samples of appearances of His power have been mentioned here. 
First, creation of camel because of its strange qualities distinguishing it from other animals as follows: 
1- It is useful for its flesh, milk, riding and carrying.
2- It is the most powerful and resistant domestic animal.
3- It could suffer thirst and hunger for successive days (about one week to ten days).
4- It could travel a long distance and pass the impassible and sandy lands that no other animal could pass. On this account, Arabs call it the ship of deserts.
5- It feeds from any barb and brushwood which is very cheap.
Second, the heavens in which so many huge spheres in the solar system have been placed without any pillar and do not move by lapse of millions of years.
Third, the mountains which are formed as a result of folding of earth, volcanoes, alluvium or in the depth of seas. 
Fourth, the earth which is spread for man's life on it.
That is right! Creation of the heavens, earth, mountains and animals shows that the world is not idle and man's creation is not purposeless.
Then, the Prophet (SA) is ordered to advise people, familiarize them with the objectives of creation,and show them the path of proximity to God and lead them in this way.
