Questions on the Explanation of the Book of Nullifiers of Islam

Question:
Does calling for the unity of religions count as apostasy?

Answer:
Yes, without a doubt. If he calls for the unity of religions while knowing that the religion of the Christians is invalid and the religion of the Jews is invalid, and he wants to equate them with Islam, this is apostasy. As for if he is ignorant and does not know, and he hears people saying this and says, "Yes, this is a good thing, gathering is good," then without a doubt this is an error and misguidance. His error and misguidance are explained to him, and if he persists, he is ruled to be an apostate because he equated disbelief with faith.
