Is the obligatory prayer valid inside the Hijr?

Question : He says: Is it permissible to pray the obligatory prayer inside the Hijr in the presence of a crowd if I am unable to pray behind the imam?

Answer : There is scholarly disagreement on this. Some said that prayer inside the Hijr is not valid, because most of the Hijr is part of the Ka'bah, and according to these scholars, prayer inside the Ka'bah is not valid if it is an obligatory prayer. Others said that prayer is valid in the middle of the Ka'bah and in the middle of the Hijr, because it is established that the Prophet (peace and blessings be upon him) prayed inside the Ka'bah in the year of the Conquest.
And what is established for voluntary prayer is established for obligatory prayer unless there is evidence to the contrary. This is the stronger position: that the obligatory and voluntary prayers inside the Ka'bah are valid. However, it is known that those responsible for the Sacred Mosque currently prevent people from praying in the Hijr, based on the opinion that prohibits the validity of prayer in the Ka'bah. The rulers' commands are to be obeyed as long as they do not command disobedience to Allah. Yes. May Allah reward you.
