The Great Mosque of Kufa, or Masjid al-Kūfa (Arabic: مسجد الكوفة المعظم‎), located in Kūfa, Iraq, is one of the earliest mosques in Islam. It was constructed in the middle of the 7th century after the Caliph Omar established the city. The mosque contains the remains of Muslim ibn ‘Aqīl - first cousin of Husayn ibn ‘Alī, his companion Hānī ibn ‘Urwa, and the revolutionary Mukhtār al-Thaqafī.
