Q. I have done intercourse with my wife during menses, so now I want to know that what is my punishment in Islam?
A. It is prohibited for a husband to have intercourse with his wife during menses. To have intercourse during menses is a major sin. (Al-Mabsoot 3/152)
Allah Ta’ala says in the Quran:
“They ask you (O Muhammad Sallallahu Alaihi Wasallam) concerning menstruation. Say, “It is impure so leave (intercourse with) women during (their period of) menstruation and do not go unto them (do not have conjugal relations with your wives) until they are cleansed (until the menstrual cycle is complete)” (Surah Baqara 2; 222)
You should regret your act and sincerely repent to Allah for such a heinous act. It is advisable for you to give some Sadaqah to compensate for your sins in invoking the forgiveness of Allah.
Allah Ta’ala Knows Best
