Prayer: Can a Ḥusayniyyah Be Incorporated into a Masjid to Expand Prayer Space?

English:

Question #423:

A ḥusayniyyah was built next to an old masjid. At present, this masjid does not have enough space to accommodate all of the people who want to perform prayer. Is it permissible to incorporate the said ḥusayniyyah to this masjid and use it as a part of the masjid?

Answer #423:

There is no problem in performing prayers in the ḥusayniyyah. However, if the ḥusayniyyah has been endowed correctly, according to shar‘, as a ḥusayniyyah, it is not permissible to transform it to a masjid or incorporate it to the adjacent masjid under the title of masjid.
