Three Levels of Piety
Piety has three levels:
One– protecting the hearts and limbs against sin and forbidden actions.
Two– protecting them against undesirable matters.
Three– protection against curiosity and whatever is not of one’s concern.
The first will grant life to the servant, the second will grant him health and power, and the third will grant him happiness and joy.
[Imam ibn al-Qayyim, al-Fawaa’id, pg56]
