He knows what is good and what is evil by means of a natural inspiration: "By the soul of man and Him who perfected it and inspired it with the knowledge of vice and virtue." (Surah ash-Shams, 91:7 - 8) (ix) Man does not feel satisfied with anything except the remembrance of Allah. His desires have no end. He soon gets fed up with anything that he gets or achieves.
It is only his attachment to Allah that can satisfy him: "Surely in the remembrance of Allah do hearts find rest!" (Surah al-Ra'd, 13:28) "Man, you strive hard to get closer to your Lord, and so you will finally meet Him." (Surah al-Inshiqaq, 84:6) (x) All the good things of the earth have been created for man.
"He it is Who created for you all that is in the earth." (Surah al-Baqarah, 2:29) "He has made subservient to you (men) whatsoever is in the heavens and in the earth." (Surah Jathiyah, 45:13) Hence, man has a right to make a lawful use of all things. (xi) Man has been created to worship his Lord alone and to take orders from Him.
Hence it is his duty to obey the commands of Allah: "I created the jinn and mankind only so that they might worship Me." (Surah al-Zariyat, 51:56) (xii) Man cannot find himself except by worshipping and remembering his Lord.
If he forgets his Lord, he forgets himself, and does not know who he is, what for he is, what he should do and where he should go: "Do not be like those who forgot Allah, and therefore He caused them to forget themselves." (Surah Hashr, 59:19) (xiii) When man leaves this world and the curtain of body which screens his soul, is removed, many realities which are hidden now, are disclosed to him: "We have removed the veil from your eyes, and so your vision will now be sharp and strong." (Surah Qaf, 50:22) (xiv) Man does not exert himself for material gains only.
To secure the material necessities of life is not his sole motive. He often moves and stirs up for the sake of higher objectives. It is possible that all his efforts be confined to seeking the pleasure of his Creator: "0 well-contented soul! Return to your Lord well-pleased, well-pleasing." (Surah al-Fajr, 89:27 - 28) "Allah has promised the believers, both men and women, gardens underneath which rivers flow and in which they shall abide.
(He has promised them) nice dwellings in the Gardens of Eden. What is more, Allah shall be pleased with them.
