The ruling on praying on the roof of a biyarah and similar structures

This is a question received from the questioner (N. A. D.) from al-Dar'iyyah, who says: What is the ruling on praying on the roof of a biyarah that is paved and roofed with cement? There was a room at the back of our mosque that we used as a storage area, built on top of the biyarah. We needed to expand the mosque's courtyard, so we removed the room and left the biyarah roofed and paved. What is the ruling on praying on top of it? Please inform us; may Allah reward you.
Answer: There is no harm in that, according to the correct view. The roofs of biyarahs and similar structures, as well as courtyards and pathways, are all places where one may pray without any harm, as long as they are pure in appearance. What is underneath is not considered; the criterion is the appearance. Yes.
