Spiritual Retreat: Intentionally Leaving the Place of Iʿtikaf for Unnecessary Matters

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 1752

If a muʿtakif leaves the place of iʿtikāf – intentionally, of his own choice, and while knowing the religious law – for a matter that is neither necessary nor one for which a muʿtakif is permitted to leave, his iʿtikāf becomes invalid.
