Is it permissible for a false witness to perform the ritual of the Adhan (call to prayer) in the mosque, knowing that he does not perform it correctly in its wording?

The ritual of the Athan (call to prayer) is a great one and should be performed by a trustworthy and upright individual. The Athan of a morally corrupt person (fasiq) is valid and sufficient, but it is disliked according to the unanimous agreement of the Shafi'i and Hanafi schools of thought. Whoever does not perform the Athan well should not undertake it, especially if they are a fasiq and make errors in it (lahn). If the error in the Athan does not change the meaning, it does not affect its validity according to the majority of jurists, but it is disliked. However, if it changes the meaning, the Athan becomes invalid.
