Happiness Fun And Pleasure

Ustadh Nouman Ali Khan discusses the verse from Surah Hadeed, Allah summarizes the things that most human beings chase after. 
“Know that the life of this world is but amusement and diversion and adornment and boasting to one another and competition in increase of wealth and children - like the example of a rain whose [resulting] plant growth pleases the tillers; then it dries and you see it turned yellow; then it becomes [scattered] debris. And in the Hereafter is severe punishment and forgiveness from Allah and contentment. And what is the worldly life except for the chattels of deception.”
Allah says in these verses that almost our entire life is consumed by our endless needs and things that we find pleasure in. but the same things that we chased all our lives are exactly those things in which we lose interest as we reach the dwindling years of our life.

Also, it is said in the above verse of the Qur'an that at the end is eternal and intense punishment and we will not get used to the punishment of Jahannam.The desires and pain of this world one can get used to it but the pain of hell we will not get used to it.

But there is hope. Allah says -"Forgiveness is from Allah, that is permanent and Ridwaan.” This means incredible or total contentment. In this world, whatever it is that we are running after, it will never satisfy us. But in Jannah we will be in peace and satisfaction.
