I've read lately in the following link http://fatherbassit.com/books/christ/trinty/trinty7.htm
that Quran disagree with the term: the father , the son and the Holy spirit, But Quran said instead Allah, the Word, and the Spirit.
But Why Muslim should combine the three things together, or can we combine together
why we just say Allah is the only God
and Jesus, Mohammad, Ibraham are the messengers of Allah
and we still believe in the spirit and the holy spirit but why don't we just say as Allah said in Quran: " And they ask you (O Muhammad) concerning the Ruh (the Spirit); Say: "The Ruh (the Spirit): it is one of the things, the knowledge of which is only with my Lord. And of knowledge, you (mankind) have been given only a little." Quran 17:85
