Ain al-Kheil Mosque, also known as al-Azhar Mosque, is a historical mosque located in Fes el Bali, Fes, Morocco. The mosque, which was first built in the late 12th century AD during the Almohad period, is notable for its association with the Andalusian Muslim scholar and Sufi master, Ibn Arabi, who came to this mosque for prayer and meditation during his stay in Fes in the 1190s. The mosque was renovated in the past years after some of its parts were destroyed. Ain al-Kheil Mosque was inscribed as a UNESCO World Heritage Site in 1981 as part of Medina of Fez.
