The Great Mosque of Kufa (Arabic: مَسْجِد ٱلْكُوفَة, romanized: Masjid al-Kūfa) is one of the earliest surviving mosques in the world, located in Kufa, Iraq. The mosque was founded in 638 AD and later rebuilt and expanded. A holy site in Shia Islam, it is the place where Ali, the cousin and son-in-law of the Islamic prophet Muhammad, the first Shia Imam and the fourth Sunni Rashidun caliph, lived and led prayers. He was fatally wounded in the mosque, with his injuries ultimately leading to his death two days later. The mosque also contains the shrines of Muslim ibn Aqil, Hani ibn Urwa, and al-Mukhtar, making it an important pilgrimage site for Shia Muslims.
