﴿ وَإِذَا ٱنقَلَبُوٓا۟ إِلَىٰٓ أَهْلِهِمُ ٱنقَلَبُوا۟ فَكِهِينَ ﴾

“and whenever they return to people of their own kind, they return full of jests;”

One who disregards his worldly considerations for the sake of the Hereafter is regarded as a fool and becomes diminished in the eyes of the worldly wise. But when the Hereafter comes, it will appear that the really wise ones were those who were considered foolish in the present world.
