This world is a prison for the Mu’min and the Jannat of the kaafir

Rasoolullah (Sallallahu alaihi wa Sallam) said:
“This world is a prison for the Mu’min and the Jannat of the kaafir.”
Comment: The Mu’min [Believer] has shunned delights and faced up to hardships [in this world]. He is, therefore, like in a prison. The kaafir on the other hand is freely engaged in pleasures and entertainment. This world is, therefore, like Jannat to him. (Mirqaat)
