Does the superintendent of the waqf have the authority to expand the imam's house by taking a portion of the prayer area for obligatory prayers or by building on land adjacent to the mosque, especially given that some mosque administrators do not build spacious houses for imams?

The expansion of the Imam's house undertaken by officials is a righteous deed for which they will be rewarded. If there is vacant land next to the mosque, the expansion should be done there by building an independent house or an addition to the first house, and no consideration should be given to distorting the image. However, if external construction is not possible, and the Imam's house becomes cramped, and there is surplus space from the mosque's courtyard or its facilities, other than the prayer area, it is permissible to add some of this surplus to the Imam's house. Similarly, if there is a prayer room (musalla) attached to the mosque where the five daily prayers are not performed and which is not needed by the worshippers, and there is no way to expand the Imam's house except by taking from it, then that is permissible. A group of scholars has permitted altering the form of an endowment for the sake of benefit, among them Sheikh al-Islam Ibn Taymiyyah. He cited incidents involving Umar and Uthman as evidence, and argued that benefit is pursued in the form of construction, and it changes according to eras and regions.
