Allah has inflicted Man with desires and has given him means to control them:

The animal spends its life in tranquility, peace and safety, because its instincts are controlled instinctively, while man's lusts, desires and inclinations have no limits. For example, when a wild animal gets hungry, it eats its prey, and it never preys on other animals once it is sated. Unlike the animal, man's hunger for money can never be satisfied. Also, when he is addicted to sex, he may commit suicide. Furthermore, his obsession with lusts, his love for collecting money, and his love for superiority may lead him to build his wealth at the expense of others' poverty. Man may act in such a way, because his desires are not disciplined instinctively, as Allah the Almighty has charged him with the task of controlling his lusts and granted him the means to do that; these means are represented by sound thinking and free will, which some scholars call: the power of free will. This is what made the Islamic creed extremely critical; the conviction, the understanding, and the creed are the motives which direct man’s energies, desires and behavior. Actually, when these concepts are applied correctly, man’s behavior will be healthy, but if they are applied wrongly, man’s behavior will be unhealthy. Before elaborating this point, let me ask you this question: who are you, O man? You are a set of concepts, so if these concepts are sound, you will live peacefully in the worldly life and be happy for ETERNITY in Paradise.
