Q: My father built a Masjid (mosque) at his own expense in Makkah Al-Mukarramah. My father assumes all its expenditures such as the salaries of the Imam and Mu'adhin (caller to Prayer), electricity and water bills and any other expenditure. Since the Masjid is on the first floor, its level became lower than the surrounding area which has filled with ruins. So, my father intends to pull it down and rebuild it. The main reason behind the intention of pulling the Masjid down and rebuilding it is the fact that the area surrounding it is filled with ruins due to the fall of torrents which makes the level of the Masjid lower than it. The Masjid is now three meters high. If we fill it with earth for one meter, it will only be two meters high. This two-meter height of the Masjid does not allow (Part No. 6; Page No. 231) us to fix ceiling fans and other needs of the Masjids. If we pull the Masjid down, we will rebuild it according to the following description:1-Firstly, after being pulled down, the Masjid is to be filled one meter high so it becomes higher.2-One third of the area of the first floor is to be assigned for a lavatory for Wudu' (ablution), for there is no lavatory in the first building of the Masjid. The remaining two thirds of the area will be shops to be rented. The rent of these shops is to be spent on the expenditure of the Masjid in the present, future and even after my father's death.3-The first floor will be the Masjid as it was before being pulled down followed by the Minaret.4-The Masjid is called 'Hussein Najjar Masjid'.I would like to have a Fatwa from your Eminence to know whether it is permissible for my father to pull the Masjid down and rebuild it as mentioned in detail or not. I appreciate your guidance.
