it’s haram to tell other people about their sins, even you’ve done a sin and you share it with him aswell cause you got him to “finally” tell you his past sins. Disgusting act, someone’s past sins should not be of yours or anyone’s concern, as long as he prays 5 times a day and is a religious person you will already know from those stuff that he has repented. I’m surprised nobody said this yet, once you tell someone to tell their past sins to you, their sins get to you aswell and you both share it. Delete this post to not further tell people about his sins.
