Spiritual Retreat: A Woman Becoming Haʾid After the Second Day of Iʿtikaf

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 1763

If a woman who is performing iʿtikāf becomes ḥāʾiḍ after the completion of the second day of iʿtikāf, it is obligatory for her to leave the mosque immediately. And based on obligatory precaution, it is necessary for her to make up the iʿtikāf unless from the outset she had stipulated a condition of returning (i.e. a condition of leaving the iʿtikāf in the middle of it if a problem arises), the details of which were mentioned in Ruling 1759.
