The Monk-- So, Abu-Salamah, you believe in all what your Prophet mentioned in your Book and that (this book) was inspired by God?
The Moslem-- Yes, everything mentioned in the Koran was inspired to Mohammed.
The Monk-- The Koran doesn't mention that the Christ is the Spirit of God and his Word given by God to Mary?
The Moslem-- Not eternal (word) but created.
The Monk-- Was God, at any time, dumb, deaf, or empty from any word or spirit?
The Moslem--God forbid! God, his Word and Spirit are always (present).
The Monk-- Is God's Word Creator or created?
The Moslem-- Creator.
The Monk-- You worship God along with his Spirit and Word, isn't it?
The Moslem-- I adore God, His Word and His Spirit.
The Monk-- Say now, then, " I believe in God, in His Spirit and in His Word."
The Moslem-- I believe in God and in His Spirit and in His Word. But I do not make them three, but one God.
The Monk-- This is my opinion, too; and my beliefs and those of all Christians of Orthodox faith. I like now to explain the meanings of the Holy Eternity: the Father is God; the Son is His Word; and the third (person is) the Holy Spirit.
The Prince was laying down. He then stood up, glanced to the Moslem, laughed and told him,-- " Abu-Salamah, the Monk Christianized you and introduced you to the Christian's religion; you are then Christian."
Abu-Salamah was furious. Then, a jurisprudent called Abul-Fadl Al-Halabi, told his friends: If you had permitted me from the beginning, I had a dialogue with the Monk and I showed you his defeat. Afterwards, he looked at the Prince and said, -- "Be informed, O Prince, that the non-believers are in the fire (in the hell) and whoever approaches them burns himself, and Satan who is the spirit of the tyranny speaks through their mouths."
