Someone asked Hassan Al Basri:

"What is the secret of your religiousness?"

He replied :

"I understood 4 things:

1. I understood that my rizq cannot be taken by anyone, so my heart became content.

2. I understood that no one can do my actions (worship) for me, so I started doing them myself.

3. I understood that Allah is watching me, so I became ashamed to do wrong.

4. I understood that death is waiting for me, so I started to prepare for my meeting with Allah."

May Allah grant us this understanding, and the ability to act according to it. Ameen
