According to Dr. Shahroor:
The definitions of sins <fahisha> can be found in the following verses:
- “Do not marry the women who were previously married to your fathers-existing marriages are exempted, for it is a gross offense <fahisha>, and an abominable act.” (4/22), Also 4/23 contains the Lower limits.
- “Lot said to his people, “You commit such an abomination <fahisha>; no one in the world has done it before!” (7/80)
- “You shall not commit adultery; it is a gross sin <fahisha>, and an evil behavior.” (17/32)
So, the “obvious’ sins are 1) Adultery, 2) Homosexuality, 3) Incest.
As for “hidden” sins, this is found in 4/128 where a man attempts to have intercourse with his wife from other than what GOD has allowed:
- “If a woman fears desertion or abstainment from her husband, the couple shall try to reconcile their differences, for conciliation is best for them. Selfishness is a human trait, and if you do good and lead a righteous life, GOD is fully Cognizant of everything you do.” (4/128)
Shahroor explains that the reason a man may abstain or not have sex with his wife is if she refuses to have sex with him beyond what GOD has allowed, thus it is upto them to reconcile.
