Waqf is an Islamic endowment of property or assets donated for charitable or religious purposes. The word 'Waqf' is an Arabic term that means a 'charitable trust'. This trust typically holds assets, and the income generated from them is used for the intended purposes. In India, such endowments are governed under the Waqf Act and the assets are overseen by the Waqf Board. Once donated, the property cannot be taken back and must always be used for the intended religious or charitable purposes.
