Is the marriage contract valid if performed by a mu'adhdhin who practices sorcery and magic?

Question:
He asks: Is the marriage contract valid if the mu'adhdhin who performed the contract practices sorcery and magic?

Answer:
If he practices sorcery and magic, he is a disbeliever; the sorcerer is a disbeliever. It is not permissible for him to oversee the marriage contract. Yes.
However, note that the marriage contract is not the one made by the mu'adhdhin. The one who makes the contract is the one who gives the offer and acceptance. The offer comes from the husband or his guardian, and the acceptance comes from the guardian of the woman or his representative, and the acceptance comes from the husband or his representative. This person is merely an overseer of the contract.
So if the offer and acceptance are completed between the husband and the woman's guardian, the marriage is contracted, even if they are not with a mu'adhdhin. If they are not with a mu'adhdhin, if the offer and acceptance occur, the marriage is contracted. Yes.
