Ruling on disposing of a piece of land in one of the Masjid's corners which cannot be used in the Masjid

Q: What is the ruling on using a piece of land outside but annexed to Al-Rawati` Masjid (mosque) to build a house for the Imam (leader of congregational Prayer) of the Masjid under his own supervision? He mentioned that the land area is 7 x 6 meters. It cannot be added to the Masjid because it is too close to the market, and the Qiblah (direction faced for Prayer) is diverted. The Masjid is also large, and does not need this extension. When the mentioned land is used to build a house for the Imam of the Masjid, it will be a Waqf (endowment) for the Masjid to be used by the Imam or the Mu'adhin (caller to Prayer), whoever needs it. If they both need it, it shall be divided among them.

A: If the situation is as mentioned by His Eminence, Shaykh `Abdul-Rahman ibn Firyan, that this land cannot be added to the Masjid; (Part No. 16; Page No. 56) that the Masjid is wide enough; you want to use it to build a house as a Waqf for the Imam or the Mu'adhin of the Masjid; as building on this piece of land in the mentioned way does not render it out of the Masjid; and this brings benefit to the Masjid more than if it had been annexed to it, the Committee declares that it is permissible, provided that it is done under the supervision of Shaykh `Abdul-Rahman, and that the mentioned land is registered as a Waqf after building on it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
