The ruling on the imam saying after the prayer: May Allah forgive us and you

This is a question sent by the listener Abdul-Rahman Ali Saleh al-Zahrani from al-Mandiq in the land of Zahran. He says: I see some imams, after they finish the prayer and turn their faces toward the worshippers, say in a loud voice: "May Allah forgive us and you." Did this come from the Prophet (peace and blessings be upon him)?
Answer: There is no basis for this, namely for him to turn to the worshippers and say: "May Allah forgive us and you." There is no basis for this, and nothing like this has reached us from the Prophet (peace and blessings be upon him). It is considered a religious innovation with no justification. Rather, when he says the closing salam, he should say: "I seek forgiveness from Allah three times, O Allah, You are Peace and from You comes peace. Blessed are You, O Owner of Majesty and Honor." Then he turns to the people in all five prayer times; he turns after this. And when he turns, he says: "There is no god but Allah alone, with no partner. His is the dominion and His is the praise, and He is over all things competent," once or three times. And he says: "There is no power and no strength except by Allah, there is no god but Allah, and we worship none but Him. His is the blessing, His is the favor, and His is the good praise. There is no god but Allah, sincere to Him in religion, even if the disbelievers dislike. O Allah, there is no one who can prevent what You have given, and there is no one who can give what You have withheld, and no one possessing power can benefit You with his power."
The one praying behind the imam is like him; he says the same things when he says the salam, just as the imam does. And he adds in Fajr and Maghrib: "There is no god but Allah alone, with no partner. His is the dominion and His is the praise. He gives life and He causes death, and He is over all things competent," ten times. He adds this in Maghrib and Fajr, as the Sunnah from the Prophet (peace and blessings be upon him) has it. Then it is recommended that he say after this: "Glory be to Allah, praise be to Allah, and Allah is the Greatest," thirty-three times... "Glory be to Allah, praise be to Allah, and Allah is the Greatest," thirty-three times. And he completes the hundred by saying: "There is no god but Allah alone, with no partner. His is the dominion and His is the praise, and He is over all things competent." Then he recites the Verse of the Throne, then he recites and the two chapters of seeking refuge. This is the best after every prayer. And in Maghrib and Fajr, he adds by reciting and the two chapters of seeking refuge three times in Fajr and Maghrib, at the beginning of the night and the beginning of the day, as the Sunnah from the Prophet (peace and blessings be upon him) has it. This is what is prescribed after every prayer. As for him saying to the congregation: "May Allah forgive us and you" in a loud voice, or "May Allah guide you," or "May Allah accept from us and from you," there is no basis for this. But if he prays for them between himself and himself, in his heart, praying for his Muslim brothers, there is nothing wrong with it. But in a loud voice, making it a habit, there is no basis for it. Yes.
