The ruling on the prayer of a person who is confined in a closed space where he does not know the direction of the qiblah

Question:
And regarding the Shaykh who is confined in a closed space, who does not know the direction, and no specific direction is predominant for him, does he pray in every direction, such as praying the Zuhr prayer in one direction and the 'Asr prayer in another, or does he establish a fixed qiblah for himself?

Answer:
He should make an effort to determine the direction, make an effort, and pray all the prayers based on his effort. He prays, and praise be to Allah, according to his condition and what he knows. How can he make an effort to determine the direction when he does not know the direction, in a closed, soundproof place where he does not know the direction, unless he has a compass device that indicates the direction, in which case he uses it. But if he does not have anything by which he can know the direction or distinguish between the directions, he prays according to his condition.
