Our mosque has a slight deviation from the qiblah direction to the left; what is the ruling on praying in it?

Question:
He says: Honorable Shaykh, our mosque has a slight deviation to the left, and we have been praying in it for a long time. It is a mosque of times, and it is difficult for us to deviate to the right. What is your opinion on this?

Answer:
The fatwa issued on this matter is that in old mosques, one prays in their current state, and their prayers are valid if the deviation is slight. As for if they are rebuilt, their orientation should be corrected; if they are rebuilt, their orientation should be corrected and they should face the qiblah exactly, because now, praise be to Allah, devices have been found that determine the qiblah direction, unlike the past when they did not have devices and would use their best judgment. Their prayers are valid, God willing, and they are in a good state. However, since it is possible for us now to correct the direction, this is obligatory upon rebuilding. As for existing mosques with a slight deviation, there is no harm in praying in them. Yes.
