The Ruling on One Who Advocates for the Convergence of Religions

Question:
May Allah reward you, Your Eminence, father. The questioner says: Among our own people, and those who speak our language, there are those who advocate for the convergence of religions. Is such a person a disbeliever in and of himself? And what is obligatory toward those like him?

Answer:
If he is ignorant, he must learn. But if he is deliberate, or if he knows that the religion of the Christians is the Trinity, and the religion of the Jews is disbelief and atheism, it is not permissible for him to equate it with Islam. Then, even if we assume that the religion of the Jews and the religion of the Christians remained as it was, unchanged and unaltered, the Qur'an may have abrogated the Shari'ah of Muhammad (peace and blessings be upon him). So no religion remains except the religion of Islam, which Muhammad (peace and blessings be upon him) brought. Yes.
