Prayer on the Roof of the Ka'bah and in the Hijr

Question:
Honorable Shaykh, may Allah grant you success, I hope you will clarify for me the issue of praying on the roof of the Ka'bah and praying in the Hijr.

Answer:
You enter the Hijr and pray. It is recommended for the one who enters to enter the Hijr and pray, facing the Ka'bah while you are in the Hijr, facing the Ka'bah while you are in the Hijr. It is not sufficient to face the wall of the Hijr, because they say the wall is a precaution; it may be outside, outside the Ka'bah. It is not on the foundations of Ibrahim; the wall of the Hijr is not on the foundations of Ibrahim, but it is included only as protection for the corner. So you pray with the Ka'bah in front of you in the voluntary prayer, but as for the obligatory prayer, you do not pray to the corner. Likewise, prayer on the roof of the Ka'bah: if it happens that you climbed onto the roof of the Ka'bah, it is permissible to pray a voluntary prayer, but there must be something of the wall of the Ka'bah in front of you, elevated, something of the wall of the Ka'bah, the structures that are placed on the roofs. The elevated wall above the roof of the Ka'bah is sufficient.
