In The Name of Allah, The Most Merciful, The Bestower of Mercy.
Imam Ibnul Jawzi [may Allah have mercy upon him] said:
Know that (blameworthy, forbidden, or unrestrained) desires entices a person towards immediate pleasures without considering the evil repercussions; entice towards short-lived pleasures, despite the fact that they are a cause of pain and harm in this life and a barrier to pleasure in the afterlife. As for sensible people, they keep away from pleasures that will lead to pain, and desires whose result will be regret. This is enough as praise regarding what sound intellect necessitates and a rebuke against desires. Know that desires can overcome a person in the different fields of study, removes one from the confines of sound reasoning and enters him (or her) into behaviour that is tantamount to madness (or folly). It might enter affairs of knowledge and thus leads a person to oppose that which sound knowledge commands, and it might enter Zuhd and thus leads one to Riyaa.
A sensible person should know that those who are addicted to lowly desires reach a state in which they no longer enjoy themselves, but at the same time, they are unable to abandon those desires, because it becomes as if it is a necessity of life. And due to this, you’ll find that alcoholics and sex addicts do not even enjoy a tenth of those desires, but they put themselves in a perilous situation that compels them to keep on returning to the act. However, if based on clear-sightedness the beautification of those lowly desires ceases, a person realises that one was exposed to some ruin that is contrary to well-being, a situation of grief instead of happiness, whilst seeking after pleasure; so, one resembles an animal that was led to a trap, but neither reached the thing that was utilised to lure it into the trap nor able to escape.
A person should ponder upon the fact that a human being was not created to fulfil desires; rather the human being was facilitated (with sound knowledge based on the divine revelation and uncorrupted perception) to reflect on the consequences of one’s actions and perform righteous deeds for the Afterlife. An animal receives pleasure through eating, drinking and sex much more than a human being, whilst living a life devoid of reflection and concern. Therefore, it is drawn towards its desires due to being ignorant of the outcomes of its actions (i.e. it does not possess the knowledge given to humans through sound reasoning and reflection guided by the divine revelation).
A person should ponder upon the consequences of desires because many people are deprived of virtue and find themselves in a state of depravity due to it. Many types of (unhealthy) food lead to illness due to an unrestrained desire (for them), and many mistakes violate one’s honour, lead to an evil mention of a person as well as the guilt of sinning due to unrestrained desires, yet one still does not give thought to anything else except their desires! The best description regarding this is that of one person in a tannery because such an individual does not really notice its smell properly until after exiting and then realises where he (or she) was.
A sensible person should imagine the dishonour that accompanies desires and the harm that results from those pleasures, for indeed one will see that- in most cases- they occur as a result of those desires and pleasures. A person should think about how (the consequences of unrestrained desires and pleasures do affect) others, then ponder and get a hint of its (unpraiseworthy) outcomes, for indeed one will see the blameworthiness of that which is known regarding them if found guilty. A person should reflect upon those pleasures because (sound) intellect (or sound perception guided by the pure divine revelation) will make one realise that they are nothing more than desires and a state of blindness.
A person should contemplate on the honour a person receives due to being given the upper hand and the humiliation found in subjugation, for indeed there is none who overcomes desires except that their honour is strengthened; and there is none who is subjugated by desires except that they will find humiliation and subjugation in one’s soul. A person should contemplate the benefits of opposing one’s desires, such as the commendation attached to it in this worldly life, the safety of the soul and safeguarding of one’s honour, as well as reward in the afterlife.

We ask Allah:
يَا حَيُّ يَا قَيُّومُ بِرَحْمَتِكَ أَسْتَغيثُ أَصْلِحْ لِي شَأْنِيَ كُلَّهُ وَلاَ تَكِلْنِي إِلَى نَفْسِي طَرْفَةَ عَيْنٍ
O Ever Living! O The Self Subsisting, Upon Whom Everything Depends! By Your mercy I seek assistance; rectify for me all of my affairs and do not leave me to myself, even for the blink of an eye. [Imaam Albaani declared it Hasan in Silsilah As-Saheehah Number 227]
