The ruling on praying behind an imam who says: "As-salamu alaykum" in the closing salam
Machine translationRead the Arabic original
Question:
He says: Honorable Shaykh, may Allah grant you success. A person leads people in prayer, but he has a lisp. When he says the salam, he says "As-salamu alaykum" instead of "As-salamu alaykum" unintentionally, because of the meaning of death. Is our prayer behind him valid?
Answer:
His prayer is not valid except for one who is like him. As for the one who is sound, the prayer of one who drops some letters due to a gap in his teeth is not valid. Yes.
