Prayer in Congregation for Employees in the Government Office

Question:
In some government offices, the midday prayer is held in the same administration building, and they call the adhan, and their adhan can be heard outside the premises. Is their prayer valid? It is known that there is a mosque near some of these offices.

Answer:
By Allah, this issue has been researched, and fatwas have been issued by Shaykh 'Abd al-'Aziz stating that it is obligatory for them to pray in the mosque.
This is a fatwa that has a strong perspective from the standpoint of evidence; for Allah has made prayer in the mosques obligatory without doubt. The Prophet (peace and blessings be upon him) said: , and He threatened those who neglect prayer in the mosque by saying that their houses would be burned with fire, and He did not ask whether they pray in their homes in congregation or not?
And in the hadith, or in the athar from 'Ali, whether marfu' or mawquf, it is said: So the truth is that the default is the obligation of prayer in the mosques, and it is not permissible to pray in the homes, nor is it permissible to pray in congregation outside the mosques. However, a problem arose that was raised by some of the people in government offices. They say: If we go to the mosque, the work will be disrupted. Perhaps, for example, the employees would go to their homes and not pray and not be disciplined. Also, some of them, if we go to the mosque and leave them, they might not pray; they might hide and go to another place. Whereas if we pray in the office, we can keep them in check, monitor them, and inspect them, and the benefit of praying in the office would be great. So from this angle, a problem arose, and the Muslims should fear Allah (Glorified and Exalted is He).
If their prayer in the mosque does not lead to dangers regarding the neglect of work, or the absence of some people, or the manipulation by some people, then it is obligatory. The default is the obligation of prayer in mosques; this is the default. But if harms occur, then their prayer in their office, with their supervision and monitoring and the regulation of work, falls under the category of dispensations (rukhsah). It is informed of dispensations, meaning there are dispensations, dispensations.
