The classical waqf concerned real estate and durable objects. Its foundation is prophetic: Umar ibn al-Khattab acquired land at Khaybar and consulted the Prophet (peace and blessings of Allah be upon him), who told him: "if you wish, hold back the principal and give its yield in charity"; Umar made that land a property that could not be sold, inherited or given as a gift (al-Bukhari 2772). The classical formula that sums up the regime kept by the jurists in the waqf sheets: "hold back the principal and let the fruit flow", frozen capital, dedicated yield. The modern era reintroduces the cash waqf: dedicating a sum of money whose returns, lawfully invested, fund the cause, the principal being preserved.
Abu Hanifa rejected the waqf of money; the majority of jurists accepted the waqf of movables at least in complement to real estate, under the condition of perpetuity (Mughni al-Muhtaj ; Bidayat al-Mujtahid). The Ottoman empire made the money waqf a massive institution from the 15th to the 18th century: capital invested, returns assigned to mosques, fountains and public kitchens, with the approval of the shaykh al-islam Ebussuud Efendi (16th century).
Among the Malikis and Ibn Surayj among the Shafi'ites, the time-limited waqf is lawful: the property remains waqf for the term and then reverts to the donor's ownership; in the other schools, perpetuity is required, and the conditional gift serves as a lawful alternative for modern foundations, as for the "temporary waqf" (a share of a property's returns for 10 years to a cause).
The donor chooses: classic real-estate waqf, invested cash waqf (endowment) or waqf of securities, within the framework of the cited standards; verify the legal existence of the foundation, its nazar council and its annual report: modern transparency prolongs the probity of the classical nadir.
