Having several Musallas in many separate departments that are close to one another

Q: We seek your Eminence Fatwa (legal opinion) on the ruling of having several Musallas (praying rooms) in many separate departments that are close to one another, and located in the same building and surrounded by one fence. It should be noted that there is a large Masjid (mosque) for all departments which does not afford sufficient space for everyone only in Zhuhr (Noon) Prayer, but during others prayers there is a sufficient place to all the employees of these departments. What is the ruling on having many Musallas in these departments in other than the time of Zhuhr? As-salamu ‘alaykum warahmatullah wabarakatuh (May Allah’s Peace, Mercy, and Blessings be upon you!)

A: The people who work in these departments have to offer all obligatory Prayers in the large Masjid. If it does not have enough space to accommodate all the people in Zhuhr (Noon) Prayer, you should expand it even by building a temporary sunshade under which people may pray until it is expanded properly later on.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
