It is mentioned in a Hadeeth: “Beware of jealousy, for verily it destroys good deeds the way fire destroys wood.”
Allah ta’ala in His Infinite Wisdom which we, with our limited intelligence, cannot comprehend, distributes amongst mankind of His bounties.
Therefore, why burn the heart over someone else’s gifts, fortunes and possessions. Harbouring jealousy in the heart only harms the one who is jealous, ruins his peace of mind, torments his heart, and destroys his own good deeds.
Mawlana Shah Muhammad Ahmed (Raheemahullah) aptly conveyed the reality of jealousy in his poetry;
“Why are you burning yourself in the fire of jealousy?
Why are you walking towards the Fire of Hell?
Are you unhappy with the distribution made by
Allah, Himself?
Why are you rubbing the palms of your hands in deep regret?”
Shaykh Yunus Patel (Raheemahullah)
