Mosques
The only ones who maintain Allah’s places of worship are those who believe in Him and the Last Day, establish prayer, give charity, and fear none but Allah. It is they who are expected to be rightly guided.
9:18He only shall tend Allah's sanctuaries who believeth in Allah and the Last Day and observeth proper worship and payeth the poor-due and feareth none save Allah. For such (only) is it possible that they can be of the rightly guided.
