Hasan al Basri...

Hasan al Basri passed by a man who was opening his mouth, laughing and enjoying himself. He asked the man:
"Did Allah, the Glorified and Exalted, promise you that He will free you from Hell Fire?"

The man said, "No."
...
......"Did Allah promise you that He will give you Jannah?"

The man replied, "No."

So the Hasan Al Basri said, "Why are you laughing and enjoying yourself?"
