What is obligatory for Muslims if they find a sorcerer living among them?

Question:
May Allah reward you with good and do you well. What is required of Muslims when they are certain of the presence of a sorcerer in their area, whose evil has become widespread, whose harm has transgressed, and who practices fortune-telling and sorcery among the people?

Answer:
They are required to first reject him and warn him of Allah (Mighty and Majestic), if he claims to be a Muslim. If they do not warn him of Allah (Mighty and Majestic) and explain to him that this is incompatible with Islam, contradicts Islam, and expels him from the religion, then if he repents and desists, praise be to Allah. Otherwise, it is obligatory for them to report his case to the Muslim authority so that it can take action against him and relieve the Muslims of his evil. It is not permissible to remain silent about this, because it is a trial, evil, and disbelief in Allah (Mighty and Majestic). Yes.
