The Ruling on Praying in One's Slippers

Question:
He says in his letter: I prayed in a mosque in the Kingdom and found the imam praying in his slippers. Is this permissible? Especially since I have heard from some people that this is a sunnah (recommended practice). What is the ruling on one who looks at his watch and is distracted by side matters during the prayer? Please inform us; may Allah reward you.

Answer:
Praying in slippers is established from the Prophet (peace and blessings be upon him). (peace and blessings be upon him). Sometimes he would take them off, place them to his left, and pray without slippers. So he prayed both wearing slippers and barefoot, (peace and blessings be upon him). Therefore, if one prays in his slippers and they are clean, there is no blame on him. It is established from him (peace and blessings be upon him) that he was one day praying with his companions when Jibril informed him that there was filth in his slippers, so he took them off and continued his prayer. Then the people took off their slippers. When he finished the prayer, (peace and blessings be upon him), he said, "Why have you taken off your slippers?" They said, "We saw you take off your slippers." He said, "Jibril informed me that there was filth in them." If one enters the mosque, let him look; if he sees filth in his slippers, let him wipe it off and then pray in them. This indicates that praying in them is a sunnah (recommended practice) and obedience, and the Messenger (peace and blessings be upon him) did it. In another hadith, it is said that so differ from them, or as he (peace and blessings be upon him) said. that praying in slippers or in leather socks is a sunnah (recommended practice), differing from the practice of the Jews and the Christians.
So if he prays in them for an obligatory or voluntary prayer, there is no harm in that, but on the condition that he takes care of them and strives to keep them clean before entering the mosque. And if he takes them off when the mosque is carpeted, and places them in a specific place for slippers or at the mosque door so as not to dirty the carpet, then there is nothing wrong with that, because carpets may be affected by slippers; people may be affected by the dust or dirt that falls on them. So if he leaves his slippers at the door or in places prepared for slippers, perhaps this, if Allah wills, is appropriate in terms of caring for the cleanliness of the carpets placed in mosques. Yes.
