It has been mentioned in the narrations of Ahlulbaty that whoever does something wrong intentionally or unintentionally, or commits a sin out of ignorance about decrees of God and out of negligence toward divine Halal and Haram or already knows about the sin but has been contaminated by that sin, if this sinner enters the arena of repentance, he will certainly be subjected to divine mercy and forgiveness.
