Answered by Ustadha Shazia Ahmad
What are the repercussions of having sex during one’s period? What are the things that the man and woman should do to purify themselves?
Thank you for your question. What you mentioned is impermissible, so repentance will be necessary as well as a ritual bath.
Repentance for this enormity is a must, and one should fear the devastating consequences of fornication, spiritually and emotionally. Resolve not to go near this sin again, and if you have difficulty with your lusts, consider marriage. Please see these tips on how to repent:
Repentance from Fornication
What Are the Conditions of Making Tawba? (Transcript) – Shaykh Abdullah Misra
It is obligatory for both parties to take a ritual bath in order to be pure to pray. The woman may delay her bath until after her period is over. Once again, be sure to cease immediately from this behavior, as intercourse during menstruation can be harmful. This is just another indication that the woman is being used and objectified.
