Waqf

An Islamic endowment — a charitable trust where assets are donated permanently for a specific purpose (education, healthcare, community benefit). The assets themselves cannot be sold, gifted, or transferred; only the income they generate is used for the designated purpose. Waqf is considered a form of ongoing charity (Sadaqah Jariyah) that continues to benefit others long after the donor's death.

Historically, waqf funded mosques, universities, hospitals, and infrastructure across the Islamic world. In the modern U.S. context, waqf can be established as part of an Islamic estate plan.

Waqf is the Islamic endowment: an asset permanently dedicated to Allah, its principal locked ('detained') and its income or use directed to designated beneficiaries — the instrument through which classical Islamic civilization financed mosques, universities (al-Azhar, al-Qarawiyyin), hospitals, and water systems for a millennium. The prophetic template is Umar's orchard at Khaybar: instructed by the Prophet to 'retain the principal and give its fruits in charity' (Bukhari, Muslim), establishing the three rules that still define waqf — perpetuity (the asset cannot be sold, gifted, or inherited), a designated purpose (charitable/public, or family in a waqf ahli), and administration by a trustee (mutawalli or nazir) bound to the founder's stipulations.

Waqf is also the paradigm sadaqah jariyah, the continuing charity that benefits the giver after death (Muslim). In the U.S., waqf principles map remarkably well onto existing legal technology: irrevocable trusts, nonprofit corporations, and endowment funds all can implement waqf mechanics, and American Muslim institutions increasingly use them — mosque properties titled to nonprofit entities, community endowments like the emerging national waqf funds, donor-advised funds operated on waqf logic, and family waqf structures built as irrevocable trusts (see our Islamic Family Waqf guide).

Estate-planning integration matters: a bequest to waqf falls within the one-third wasiyyah cap, while lifetime waqf dedication is unrestricted — one reason scholars encourage endowing during life.
