Excerpts From ‘The Dispraise of [Unrestrained] Desires’ – By Imaam Ibul Jawzi [rahimahullaah]
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Ibnul Jawzi [rahimahullaah] said:
know that uncontrolled desires [i.e. the desires that violate the commands, prohibitions and pure Islamic principles] urges a person towards [engagement] in immediate pleasures without him pondering upon its evil consequences; and urges him towards short-lived pleasures, even though it is a cause of pain and harm in this life and a barrier to pleasure in the afterlife. As for a sensible person, he keeps away from pleasures whose result will be pain and desires whose result is regret. This is enough as praise regarding what sound intellect necessitates and a rebuke against uncontrolled desires.
