So let's talk Trinity again, in light of this statement that the Qur'an is perfect.
Christians of all denominations, including Catholic and Eastern Orthodox to be:
The Father, the Son, Jesus and the Holy Spirit.
Although I do not speak Arabic like Bowman, I think the Qur'an clearly states:
"And behold! God will say: O Jesus the son of Mary didst say unto men, "Worship me and my mother as gods" in derogation of Allah" Surah 5:116
So since this is patently false, that Mary is NOT part of the Trinity, that Christ never said to worship his mother, because the Bible is quite clear that the Trinity is Father Son and Holy Spirit, this proves that the Qur'an is not perfect.
Since you say you believe in the Old Testament prophets, did you know the penalty for prophesying even ONE wrong thing?
Being put to death!
"But that prophet or that dreamer of dreams shall be put to death, because he has taught rebellion against the Lord your God, who brought you out of the land of Egypt and redeemed you out of the house of slavery, to make you leave the way in which the Lord your God commanded you to walk. So you shall purge the evilfrom your midst." Deut. 13:5
And this is from the Torah, which you claim to believe in.
So because Mohammed falsely put a claim into the Qur'an, his book of prophecy and dreams, it would only make sense that he should have been put to death and the Qur'an is proved false!
