Spiritual Retreat: The Iʿtikaf of a Discerning Child (Mumayyiz)

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 1760

A valid iʿtikāf is not conditional on one having reached the age of legal responsibility (bulūgh), and iʿtikāf performed by a child who is able to discern between right and wrong (mumayyiz) is also correct.
