The Ruling on Declaring the Ignorant and the Specific Individual a Disbeliever

Question:
He asks: Is it permissible to declare the ignorant person a disbeliever, such as one who circumambulates graves while not knowing that it is an act of disbelief? And is it permissible to declare a specific individual a disbeliever, or not?

Answer:
How can he not know that it is disbelief when he recites the Qur'an and hears the Qur'an which warns against shirk (associating partners with Allah)? It is rare to find a surah that does not contain a warning against shirk. What is shirk? He must know that shirk is worshipping other than Allah (Glorified and Exalted is He). Allah commanded to worship Him alone, with no partner, in many verses, and prohibited shirk, which is worshipping other than Allah. Among its forms are calling for aid from the dead, circumambulating graves, and others. How can he not know shirk? He is a Muslim, he recites the Qur'an, he attends lessons, he hears lectures, and he hears the khutbahs, the Friday sermons.
But they say, "This is the religion of the extremists, this is the religion of the Wahhabis, this is the religion of the Khawarij." They repel people from this and do not accept the truth, and the proof has become established against them. The proof has become established against them; if the proof is not established by the Qur'an, by what is it established? Yes.
