Likewise is the case with the Muslim and the Christian. The Muslim argues for his religion from the book of the New Testament, the Gospel, and tries to prove to him the prophethood of Master Muhammad (may his glory be exalted) and the truthfulness of the religion of Islam, etc.

Likewise is the case with the Sunnis and the Shi'a. The Shi'i comes and argues for the guardianship of Amir Al-Mouminine (may his glory be exalted) from the books of the Sunnis, the oppression of the People of the House, the lack of "justice" of the Companions, and other controversial topics between the Sunnis and the Shi'a.

So the case progresses gradually, until the matter reaches us, we the Unitarians, and the "detractors." We argue against them for our religion from their own books, through the Hadiths that are in their hands—of course, some of them are allusions, and at times, expressions.
