1/ Jealousy is of the most despised ailments of the heart. It caused Iblīs to refuse obedience & be eternally cursed; it made Cain murder Abel; it blinded the sons of Isḥāq to throw their innocent brother into a well and sell him into slavery.
What are its symptoms & cures?...

2/ Symptoms:
- To be obsessed about someone else's lifestyle (why are you concerned??);
- To rejoice at someone else's misfortune (a believer should sympathize with another's misfortunes);
- To be bothered by another's success (a believer should be happy when others are!).

3/ Cures:
- Sincerely ask for a pure heart (qalb salīm)
- Say 'MashaAllah' when you hear someone's blessing & mean it
- Believe in qadr: what is meant for you is best & what you don't have is for your own good
- Understand this world vs next
- Make dua for others' blessings
