All people on Earth seek happiness–whether it’s through wealth, or love, or piety. Few realize that perfect happiness does not exist in the dunya.
When you think about it, you’ll find that hardship and pain exist with moments of great happiness. For example, you ate your favourite meal after a long time, but you feel over-full and you become tired and lazy. Or, you enjoy a wonderful hike through the woods, minus the insect bites and that bee that flew into your ear.
So be aware, and aim for higher then dunya happiness.
This is a mercy of Allah (سبحانه وتعالى). If you found the perfect happiness, and subhanallah, someone talked to you about paradise, you might say “who cares? I’ve found the perfect happiness here.”
True happiness exists only in Jannah.
May Allah (سبحانه وتعالى) unite us all in Jannah and grant us all al-Firdaus, out of His mercy.
