In Islam, ‘Irfaan (Arabic/Persian/Urdu: عرفان; Turkish: İrfan), also spelt Irfaan and Erfan, literally ‘knowledge, awareness, wisdom’, is gnosis. Islamic mysticism can be considered as a vast range that engulfs theoretical and practical and conventional mysticism and has been intertwined with sufism and in some cases they are assumed identical. However, Islamic mysticism is assumed as one of the Islamic sciences alongside theology and philosophy.
