The
Sanctuary of Imām 'Alī, also known as the
Mosque of 'Alī, located in Najaf, Iraq, is a mausoleum which Shia and Sunni Muslims believe contains the tomb of 'Alī ibn Abī Tālib, a cousin, son-in-law and companion of the Islamic prophet Muhammad. The Shī'as consider 'Alī as their first Imām and the first of the twelve caliphs of Muhammad, and the Sunnis regard him as the fourth Sunni Rashid Caliph. According to Shī'ite belief, buried next to 'Alī within this mosque are the remains of Adam and Nuh (Noah). Each year, millions of pilgrims visit the Shrine and pay tribute to Imām 'Alī.
