What is the ruling on one who denies the Sunnah and claims that a prophet will be sent?

The questioner : The questioner says: There are people now who deny the Sunnah and say that a prophet will be sent in these days. What should we do with them, since we have explained this to them and they did not return?

So that the necessary measures are taken against him and he is given the opportunity to repent so that he may turn away from this disbelief. Whoever believes that a prophet can be sent after Muhammad (peace and blessings be upon him) is a disbeliever who has exited the religion, and his blood and wealth are permissible to take, because Allah says: . If someone claims that a prophet can be sent, he is denying the Qur'an. The Prophet (peace and blessings be upon him) informed us that Allah sealed the prophets with him, and the Muslims agreed that there is no prophet after Muhammad (peace and blessings be upon him).

I say to the brother questioner: if he knows this specific person, let him contact him and warn him of Allah. If he repents, well and good; otherwise, it is obligatory for him to report him to the competent authority in order to carry out the necessary measures against him.
