Machine translationRead the Arabic original
Question:
Some people, Honorable Shaykh, the questioner says, cover their mouths while praying, and some lean against the wall if they are tired.
Answer:
It is not permissible to lean against the wall. If he is tired and unable to stand, he prays sitting down, as the Prophet (peace and blessings be upon him) said. As for covering the mouth, if it is for a need, there is nothing wrong with it. If it is not for a need, it is disliked, because it is imitating the Jews. Yes.
