Allah Ta’ala, in His Infinite Wisdom, which we —with our limited intelligence, cannot comprehend, distributes amongst mankind of His bounties. Allah Ta’ala gives wealth, intelligence, health, beauty, and all other goodness.
There is no need to burn the heart over someone else’s gifts, fortunes, and possessions. Harbouring jealousy in the heart only harms the jealous one, ruins his peace of mind, torments his heart, and destroys his own good deeds.
It narrated in a Hadith that Nabi (sallallahu' alayhi wa sallam) said:
“Beware of jealousy, for verily it destroys good deeds the way fire destroys wood.”
Maulana Shah Muhammad Ahmad Saheb (rahmatullah ‘alayh) 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?”
Expel the evil of jealousy from the heart. Seek goodness from Allah Ta’ala and make the correct effort by using the Halaal means to acquire what is permissible. Be satisfied and content with whatever is achieved.
