I heard the Prophet (ﷺ) saying, "If somebody commits a sin and then says, 'O my Lord! I have sinned,
please forgive me!' and his Lord says, 'My slave has known that he has a Lord who forgives sins and
punishes for it, I therefore have forgiven my slave (his sins).' Then he remains without committing
any sin for a while and then again commits another sin and says, 'O my Lord, I have committed
another sin, please forgive me,' and Allah says, 'My slave has known that he has a Lord who forgives
sins and punishes for it, I therefore have forgiven my slave (his sin). Then he remains without
Committing any another sin for a while and then commits another sin (for the third time) and says, 'O
my Lord, I have committed another sin, please forgive me,' and Allah says, 'My slave has known that
he has a Lord Who forgives sins and punishes for it I therefore have forgiven My slave (his sin), he
can do whatever he likes."
Sahih al-Bukhari Book 97, Hadith 132
