Cutting off body organs
If a rapist, or any man who performs a sexual act outside marriage, feels very guilty and decides to cut off his penis. Would he have committed an extra sin?
It is not allowed for any person to cut off any of his organs unless it is necessitated by medical reasons. Therefore, it is not permissible for any rapist to cut off his penis. Some Sahabah had asked the Holy Prophet about a person who does not have opportunities to satisfy his sexual desire or for a person who wants to devote himself for worship not disturbed by his sexual urge. The Holy Prophet ﷺ refused to give permission for these acts and had advised such persons to keep fast constantly which may help them reduce their sexual desire.
