Thanks! Much appreciated.
Just wondering what you thought about speaking in tongues as evidence of recieving the holy spirit, as in the day of pentecost,
First, Muslims do not accept the concept of the Trinity, or a triune godhead. We firmly believe in One God without partners or parts. According to our belief, the negation of the Trinity is one of the major reasons that God Almighty sent down Prophet Muhammad [s] after Prophet Jesus [as].
The Trinity is made up of three persons: (1) the Father "who art in Heaven", (2) the Son (Jesus), and (3) the Holy Spirit. We Muslims believe that only the first one is God, the Creator of all things. The second two (Jesus and the Holy Spirit) are creation, blessed servants of God Almighty. We reject the idea that Jesus [as] is the son of God, and we believe that he is a blessed prophet like Adam, Noah, Abraham, Moses, and Muhammad (peace be upon them all).
As for the Holy Spirit, we believe that this is the Arch-Angel Gabriel [as]. Gabriel is the highest of the Angels, commissioned by God Almighty to convey the Message from God to the Prophets. The Quran says:
“And We gave Jesus, the son of Mary, clear signs--and supported him with the Holy Spirit." (Quran, 2:87)
"We endowed the Messengers with gifts, some above others. To some of them God spoke to directly; others, He raised to degrees of honor; and to Jesus, the son of Mary, We gave clear miracles, and supported him with the Holy Spirit." (Quran, 2:253)
The Holy Spirit, i.e. Gabriel, is the one who revealed the Quran to Prophet Muhammad [s], as the Quran says:
“And when you recite the Quran, seek refuge in God...Proclaim! The Holy Spirit has brought it down from your Lord with truth, that it may make firm and strengthen those who believe, and as a guidance and glad tidings to those who have submitted to God." (Quran, 16:102)
God said to Prophet Muhammad [s]:
"Verily this is a Revelation from the Lord of the Worlds, which the Holy Spirit has brought down upon your heart." (Quran, 26:193)
And:
"Proclaim! Whosoever is an enemy to Gabriel--for surely it is he who brings down the revelation to your heart by God's Will, confirming that which was revealed before it, and guidance and glad tidings to those who believe--Whosoever is an enemy to God, His Angels and Messengers, of Gabriel and Michael--Lo! God is an enemy to those who reject Faith." (Quran, 2:97-98)
Anyways, to conclude, we say that the Holy Spirit is the Arch-Angel Gabriel [as], and not a part of, or partners with, God.
Now to answer your question (finally!): we do not believe in speaking in tongues or any such thing. If any Muslim were to claim such a thing, it would be considered an affront to the Islamic orthodoxy.
and baptism by full immersion as John always did in a river. Baptize (greek) immerse?
We believe in and affirm John the Baptist (peace be upon him), whom we consider a blessed prophet of God. The Quran says about Prophet John:
"'O John, hold fast to the Scripture!' We gave him compassion and purity, for he was righteous. He honored his parents, and was never overbearing or rebellious. Peace be upon him the day he was born, and the day he dies, and the day he shall be raised to life." (Quran, 19:12-15)
As for whether or not we believe in baptism, the answer is yes and no. When a person converts to Islam, he is instructed to have a ritual bath (ghusl), which symbolizes the washing away of spiritual impurities. However, Christians believe that the ritual bath has to do with Original Sin, the death and resurrection of Jesus. Muslims reject the idea of Original Sin, as well as the idea that Jesus [as] was the Son of God. As such, the Quran commands us to say:"The baptism of God have we received, and who is better than God to baptize? Him do we worship." (Quran, 2:138)
So to conclude, yes we have the concept of a ritual bath which is taken upon conversion to Islam. However, it is not the exact same belief as Christians.
Hope that helps.
In the Care of the Lord,
