One of the first actions that the prophet PBUH undertook upon his arrival to Madinah was building a Masjid, because it is considered as the most comfortable and educational place for the Muslim community, and from it all good deeds begin.  

Masjid maintenance involves keeping a mosque in good condition through repairs, bill payments, and other upkeep. It’s an important part of ensuring the mosque is functional and safe for use.  Masjid also needs a constant maintenance work to be always in a good condition of performing its great mission.
