Names and titles

Ali is known by many honorifics in the Islamic tradition, some of which are especially used by Shias. His main kunya (teknonym) was ʾAbū al-Ḥasan ("father of al-Hasan"). His titles include al-Murtaḍā (lit. ' one with whom is pleased ' or ' one who is chosen and contented '), Asad Allāh (lit. ' lion of God '), Ḥaydar (lit. ' lion ', the name initially her mother gave him), Amīr al-Muʾminīn (lit. ' commander of the faithful' or 'prince of the faithful '), and Imām al-Muttaqin (lit. ' leader of the God-fearing '). In particular, Twelvers consider the title of Amir al-Mu'minin to be unique to Ali. He is also referred to as Abū Turāb (lit. ' father of dust '), which might have initially been a pejorative by his enemies.
