Islam also deals in detail with private life. In this regard, the view of Islam is that no human being is an insignificant creation. Not even a purposeless creation. Therefore, Islam does not allow a person to destroy himself at his own will, lead himself astray or be careless about himself. The Qur'an says:
O Lord, you did not create me meaningless and purposeless.
--- Surah Ale-Imran-191
This consciousness makes the person aware of himself. Thus, Islam has given special importance to create awareness and a sense of responsibility in the individual. Because the core of any way of life is the 'individual' and this is why Islam always starts its journey from the individual.
Man has two natures – an inner one which is not seen and the other is an outer one which is seen. Islam gives importance to both these entities. These two entities are very close, related and complementary. Islam seeks to form the individual through the balance of these two entities.
The inner identity of man can again be divided into two things - one is 'ruh' (soul, self or soul) and the other is 'akl' (mind, reason or intellect). Islam feeds these two natures.
