What is the permissible degree of deviation from the qiblah in meters?

Question:
Honorable Shaykh, the questioner asks: What is the measure of deviation from the qiblah in meters? And is it permissible to pray in a mosque that is deviated from the qiblah by a distance of five meters?

Answer:
This is a well-known issue: whoever can see the Ka'bah must pray toward it and not deviate from it. If he deviates from it, his prayer is invalid. The one inside the Sacred Mosque who can see the Ka'bah must face it directly. He must not deviate from it.
As for the one who does not see it, being far away from it outside the Sacred Mosque, he prays toward the direction in which the Ka'bah is, even if he deviates from it. The Prophet (peace and blessings be upon him) said: So the one far from the Ka'bah faces the direction in which the Ka'bah is, even if he deviates slightly. If he deviates slightly, the deviation is forgiven.
But if he deviates greatly, and the qiblah ends up behind his back or to his side, his prayer is invalid. Yes.
