The leadership of a blind imam if he deviates slightly from the qiblah

Question:
May Allah reward you. This questioner asks, saying: Honorable Shaykh, if the blind imam is accustomed to deviating from the qiblah, but only slightly, is his leadership valid?

Answer:
Yes. A slight deviation does not harm, whether from the sighted or the blind. A slight deviation does not harm except if it is in al-Masjid al-Haram and one can see the Ka'bah. If he can see the Ka'bah, he does not deviate from it. But if he cannot see it, he prays in the direction of the Ka'bah. Even if he deviates slightly. Does this harm? No.
