The Ruling regarding the Mosques which are not Used Anymore
What is the ruling concerning the mosques which are situated in the middle of streets, and also regarding those which are situated in deserts or desolate villages and which are no longer used for performing prayers and sometimes they are contaminated by animals which enter them?
About mosques that are situated in the middle of streets, there is no way that they can be demolished, both because they are mosques and because the property on which they have been built has been devoted by someone to the mosque. Thus anyone who demolishes such a mosque should pay the price for that by building another mosque or repairing other mosques. In fact, this is an example of wasting the property itself and until there is no necessity, destroying a mosque is strictly impermissible. As regards desolate mosques in deserts and desolate villages, they should be kept in a way that they are not desecrated.
Performing bestowment in Mosque
Is it permissible to perform acts like bestowment in the mosques, and if they are permissible, should they be done after obtaining permission from the religious authority?
Performing these acts in the mosque is not prohibited and there is no need for the permission of the religious authority. However, attending to worldly acts in the mosque is considered to be makrūh and if these acts disturb the worshippers in the mosque they are prohibited.
Testifying to the Wilāyah of Amir al-Mu’mineen (‘a) in Adhān (call to prayer)
Since when has the phrase for testifying to the wilāyah of Amir al-Mu’mineen Ali (‘a) been recited in the adhān (call to prayer)?
According to some traditions, this phrase has been recited as a part of the call to prayer since the age of the Infallible Imams (‘a) but it was not widely recited in that era. Later on it became the motto of the Shiʻa school (for more information, refer to the valuable book of “al-Mustamsak”, chapter on adhān and iqāmah).
Using a Part of the Inner Chamber of the Mosque to Expand the Kitchen
In case a mosque needs a bigger kitchen as its current kitchen is too small, is it permissible to separate the kitchen from the mosque itself in order to expand it?
There is no issue with it if it doesn’t disturb the worshippers and it doesn’t reduce the place for performing prayers and it is a necessity for the mosque.
Entrance of Infidels into Mosques
Is it necessary to prevent infidels from entering the mosques?
The obligatory precaution demands that infidels be prevented from entering mosques except when they intend to research about Islam and like that.
