Someone asked Hassan al Basri r.a :
“What is the secret of your piety?”
He replied, “I understood 4 things:
1. I understood my rizq cannot be taken by anyone so my heart contended.
2. I understood no one can do my actions (worship) so I started doing them myself.
3. I understood Allah (swt) is watching me, so I felt ashamed to do wrong
4. I understood death is waiting for me so I started to prepare for my meeting Allah swt. “
