What are the punishments of past acts of homosexuality done in ignorance? Is it obligatory to tell about it to my to be spouse?

The discussion regarding the punishments for past acts of homosexuality and the obligation to disclose such acts to a future spouse is nuanced and varies between Islamic traditions.

According to Sunni scholarship, as reflected in Tafsir Ibn Kathir, the punishment for acts of fornication, which includes homosexuality, is severe. The Prophet Muhammad ﷺ is reported to have stated: I heard the Prophet (ﷺ) command that whoever commits fornication without being married should be flogged a hundred lashes and exiled for a year. Sahih al-Bukhari 86:57SunniSAHIH. This indicates that the punishment for unlawful sexual acts is serious, emphasizing the need for repentance and reformation.

In relation to past sins, the general understanding in Sunni thought is that if a person has committed such acts in ignorance and has since repented sincerely, then Allah’s mercy is vast. The emphasis is on repentance, as Allah is described as "Forgiving, Merciful." Those who genuinely repent and seek forgiveness should not feel compelled to disclose their past sins to others, including a future spouse, unless it is relevant to the marriage.

On the other hand, Shia scholarship, as discussed in Al-Kafi, similarly emphasizes the importance of repentance. It holds that if someone has acted against the commandments of Allah, they should repent and seek forgiveness. The punishments for acts like homosexuality are severe, including stoning for married offenders and flogging for unmarried ones. However, the principle of concealing one's past sins is also significant in Shia thought. If a person has repented sincerely, it is generally discouraged to disclose past sins unless it is necessary for the marriage or could affect the relationship.

In summary, both Sunni and Shia views stress the importance of sincere repentance for past acts of homosexuality. The obligation to disclose such acts to a future spouse is not a strict requirement, and individuals are encouraged to maintain their privacy regarding past sins, focusing instead on their present commitment to righteousness. For personalized guidance on this matter, it is advisable to consult a qualified local scholar.
