A mystical traveler must note the following point from the Holy Quran: Righteous deeds will affect one’s soul, and any light from the deed will be tenfold. Consequently, if one performs a righteous deed, they will be rewarded tenfold.
Due to the beneficence of the glorified God, a sin is not treated likewise. When one commits a sin, the penalty will not be greater than its corresponding misdeed. Pondering this grace will create a pure effect on one’s soul.
