The ruling on the imamah of one who wears amulets and charms

Honorable Shaykh! We have a colleague at work who sometimes leads the prayer for the workers. He has worn an amulet. What is the ruling on this man leading the prayer? If the answer is that it is not permissible, what should we do?The Shaykh: Is this the man who prays with you, and you say he is wearing an amulet? Does he lead you because the person in charge of this department appointed him, or because you elected him?The questioner: No, Shaykh! There is an imam who prays with us and is consistent in leading the workers' prayer. There is no person chosen by the administration, but he stepped forward as imam and was consistent in leading. Sometimes this imam is absent due to work or a circumstance outside of work, so this person is put forward by the worshippers?
If he was elected by the worshippers and is a deputy for the official imam, and he has this amulet in his hand, then it is obligatory for you first to advise him and explain to him that there is no good in this amulet and that it is a type of shirk (associating partners with Allah), especially if it contains symbols or forbidden invocations or the like. If he stops doing it, then Allah has guided him through your hands, and you have a reward in this. And if he does not stop, then it is obligatory that the matter be raised to the imam who appointed him, and it should be said: We do not approve of this man being your deputy. And you should choose a righteous person in his place.

The questioner: If a person enters and finds this man leading the worshippers?The Shaykh: He prays with them, and there is no blame on him.
