Allah tells us about His creation of the upper realm, which is the heavens, and the lower realm, which is the earth, and everything in them. They have been created for a true purpose, not in vain, so that

{He may requite those who do evil with that which they have done (i.e. punish them in Hell), and reward those who do good, with what is best (i.e. Paradise).} [53:31]

Then He declares Himself to be above the Shirk of those who worship others besides Him. He is independent of His creation, alone with no partner or associate. For this reason He deserves to be worshipped Alone, without partners. Then He mentions how man has been created from a Nutfah, i.e., something that is insignificant, weak and has no value - but when man becomes independent and is able to fend for himself - then he begins to dispute with his Lord, may He be exalted, and disbelieves in Him and fights His Messengers. But man was created to be a servant, not an opponent, as Allah says:

{And it is He Who has created man from water, and gave him descendants, and made Him kindred by marriage, and your Lord is capable (of all things). And they worship besides Allah, that which can neither profit them nor harm them; and the disbeliever is ever a helper (of Shaytan) against his Lord} (25:54-55).

And;

{Does not man see that We have created him from Nutfah. Yet, behold he stands as an open opponent. And he puts forth for Us a parable, and forgets his own creation. He says: "Who will give life to these bones after they are rotten and have become dust?" Say: "He will give life to them Who created them the first time! And He is the knower of every creature!"} (36:77-79).

Imam Ahmad and Ibn Majah reported that Busr bin Jahhash said: "The Messenger of Allah spat in his palm, then he said,

«Allah, may He be exalted, says : "O son of Adam, how could you be more powerful than I when I have created you from something like this, and when I have fashioned you perfectly and made you complete, you walk wearing your two garments and the earth makes a sound (beneath your feet). You collect money but do not give anything to anyone, then when the soul of a dying person reaches the throat, you say, 'I want to give in charity', but it is too late for charity."»
