Note: Avoid Jealousy And Crab Mentality

💐 In The Name Of Allah The Most Gracious The Most Merciful
💌 Even if a person appears to be successful, has impressive credentials to prove they're educated, or enjoys a luxurious lifestyle, they can't achieve happiness on the inside if their heart harbors envy and jealousy towards others. Enviously resenting people for having things that one lacks is like questioning the wisdom of Allah Subhaanahu wa Ta'aala, wondering why Allah the Most Wise gave such and such a thing to this individual while He didn't give you what they've got.
As Muslims Alhamdulillah we must train ourselves to avoid the dangerous "crabs in a bucket" mindset or "crab mentality" attitude. Preoccupying yourself with pulling others down does not make you reach success, just as calling another woman "ugly" doesn't make you prettier. Counting a person's flaws then spreading rumors about them to soothe detrimental envy does not make you better than them, in the same way blowing out someone else's candlelight to make your light shine brighter only shows you're an unkind individual who could be struggling with serious insecurity issues.
The more grateful you are to Allah Subhaanahu wa Ta'aala, the more you'll be at peace internally and focused on improving yourself instead of comparing your journey to others' unique tests.
Next time you see somebody sharing their joys to express gratitude to Allah the Most Merciful, rather than rolling your eyes at them and thinking "what a show-off" or "so what?", try to be joyful for them, or be inspired to work harder on achieving your own goals, and pray that Allah Subhaanahu wa Ta'aala increases their blessings as well as yours. The only thing we lose by being genuinely happy for other Muslims is prideful ego which prevents one from attaining actual contentment. A heart that hates to see others succeed in both worlds is an unhappy, restless and anxious heart.
To be happier for Allah's sake, focus on striving to be worthy of Allah's Love, detach yourself from the satanic quality of being envious, and make it a practice to generously mention more Muslims in your loving Du'as.

📖 Abu Huraira RadhiAllahu 'anhu narrated: Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, "Whoever wrongs his brother in his honor or anything else should resolve the matter today before it cannot be resolved with gold and silver coins. If he has good deeds to his credit, they will be taken from him according to the measure of his injustice. If he has no good deeds left, he will bear the evil deeds of the one he has oppressed."
