_Koran_. O ye who believe, repent unto God, for He loveth them who are
penitent. O ye who believe in me, who by much sin have done a great
wrong to themselves, despair not of the mercy of God, for He forgiveth
all sins. Verily He forgiveth and is merciful.
_Traditions_. Sorrow for sin is repentance. He who repents is like
him who has not sinned.
_Wise Sayings and Proverbs_. No intercession succeeds so effectually
as repentance.
The most truthful man is he who is true to his repentance.
Two sins only God does not forgive--worship of false gods and injury to
men.
