Someone asked Al-Hasan Al-Basri (may God have mercy on him): “What is the secret to your piety?”
He replied: “I understood four things:
1. I understood that my rizq (provision/sustenance decreed by Allah) 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.”Timeless Seeds of Advice by B. B. Abdulla
