In Islam, ‘Irfān (Arabic/Persian/Urdu: عرفان, also spelt Irfaan and Erfan, literally ‘knowing, awareness’) is gnosis; however, it also refers to Islamic mysticism. Those with the name are sometimes referred to as having an insight into the unseen. Irfan is also a Muslim given name, usually for males.
The concept of Irfan overlaps considerably with Sufism in both meaning and content. A large number of the Twelve Imāms appear in numerous Sufi orders. In Twelver Shiism on the other hand, the term refers specifically to gnosis that can be revealed strictly within the confines of Islam.
