The Ruling on Takfir and an Explanation of Its Severity

Question:
Does an ignorant person become a disbeliever because of his ignorance? And what is your opinion regarding some people using the word "disbelief" against one another, even if it is merely in speech?

Answer:
The practice of takfir (declaring someone a disbeliever) is a serious matter. It is not permissible for anyone to intervene in it except the people of knowledge and those who are aware of who deserves these rulings. For this to occur among people, the ignorant, and the beginners is a great error. It is not permissible to rule that a Muslim who testifies that there is no god but Allah and that Muhammad is the Messenger of Allah is a disbeliever, except if he commits one of the nullifiers of Islam. Only the people of knowledge truly know the nullifiers of Islam. Therefore, it is obligatory to ask the people of knowledge about a person who has done such-and-such: what is his ruling?
One should ask the people of knowledge. As for issuing rulings arbitrarily, with some of us judging others, this is not permissible. Rather, we ask the people of knowledge: such-and-such person did such-and-such, he spoke such-and-such, so what is his ruling? The people of knowledge know the nullifiers of Islam, and they know who deserves takfir and who does not. One should return to the people of knowledge in this serious matter, in which it is not permissible for anyone other than its specialists and those with expertise in it to intervene. Yes.
