Al-Kāfi

2. Abu Ali al-Ash’ari has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “Once I read the words of Allah, the Most Majestic, the Most Holy, before one of the two Imam (a.s.) . . those who avoid the major sins and indecent acts except the al-Lamam ones . . (53:33) The Imam said, ‘It is a thing after a thing, that is, a sin after a sin that a servant (of Allah) commits.’”
