Naffīr () is an Arabic word used in parts of Sudan (including Kordofan, Darfur, parts of the Nuba mountains and Kassala) to describe particular types of communal work undertakings. Naffīr has been described as including a group recruited through family networks, in-laws and village neighbors for some particular purpose, which then disbands when that purpose is fulfilled (Manger, 1987). An alternative, more recent, definition describes naffīr as “to bring someone together from the neighborhood or community to carry out a certain project, such as building a house or providing help during the harvest season.” (Source: 'Conceptual analysis of volunteer', 2004)
