What is the ruling on one who intentionally mispronounces (lahn) in a way that changes the meaning during the first taslimah and then repeats it correctly?

Peace (saying "As-salamu alaykum") is one of the pillars of prayer according to the majority of scholars, and this is the correct view, based on the saying of the Prophet, peace be upon him: "And its تحليل (making lawful what was unlawful during prayer) is the tasleem (the salutation of peace)." Therefore, whoever intentionally makes an error (lahn) in the tasleem, their prayer becomes invalid and must be repeated, because they uttered human speech before exiting the prayer. However, if one makes an error unintentionally (sahw), their prayer is not invalidated, but they must perform the correct tasleem, and it is legislated for them to perform the prostration of forgetfulness (sujud as-sahw). The minimum sufficient form of tasleem is "As-salamu alaykum," and whoever omits a single letter from it, their tasleem is not valid.
