The Trinity?

Why does Allah not understand the Trinity

Despite the fact there is ample manuscript evidence of the Bible’s reliability the Qur’an teaches that the Bible has been corrupted in translation and that the Trinity is a belief in three Gods. "Abraham was neither Jew nor Christian; but he was sound in the faith, and not of those who add gods to God"(Sura 3:67). The Qur’an understanding of the Trinity is three Gods; Father God, Mother God (Mary), Baby God (Jesus) therefore Christians are viewed as polytheists, thus guilty of the unpardonable sin (shirk) of adding gods to the Godhead. "Believe therefore in God and his apostles, and say not, ‘Three:’ (there is a Trinity) Forbear it will be better for you. God is only one God! Far be it from His glory that He should have a son!"(Sura 4:171) "Infidels now are they who say, ‘Verily God is the Messiah Ibn Maryam (son of Mary)!" (Sura 5:72)
The Muslim misconception is 1+1+1=3, whereas the Christian concept is 1x1x1=1.
The Muslim cannot grasp the concept of God being so loving that He would sacrifice His only begotten Son for the sins of man. Yet, that is exactly what John the Baptist was saying when he called Jesus the Lamb of God that takes away the sins of the world (John 1:29).

The Muslim challenge to Christian theology has been so public as to have anti-Trinitarian verses from the Qur’an printed on their first gold coins in 694 by Abd al-Malik. "There is no God but God (Allah) alone, he has no companion. Muhammed is the Prophet of God, who sent him with guidance and the religion of the truth to make it prevail over all religion." (9:33) "He is God, one, eternal; he does not beget nor is he begotten." (112:1-3) The same verses he had written on the walls of the Dome of the Rock Mosque he built in Jerusalem in 691. This was to rival the Christian Church of the Holy Sepulchre and make a strong polemic statement against Christian doctrine. Other anti-Trinitarian verses repeatedly decorate the walls. Islam is clearly antichrist in its history, its theology and its scripture the Qur’an. The placement of this mosque on the site of the old Jewish temple was a statement against the Jews.
The Qur’an clearly teaches, "And when the sacred months are passed, kill those who join other gods with God wherever ye shall find them; and seize them, besiege them, and lay wait for them with every kind of ambush: but if they shall convert, and observe prayer, and pay the obligatory alms, then let them go their way, for God is Gracious, Merciful" "Christians say, ‘The Messiah is a son of God.’ Such the sayings in their mouths! They resemble the saying of the Infidels of old! God do battle with them! How are they misguided." "O Prophet! Strive against the disbelievers and the hypocrites! Be harsh with them. Their ultimate abode is hell, a hapless journey’s-end" (Sura 9:5,30,73 "IMMUNITY"). Apparently it is not enough that the infidels are going to hell, some Muslims, with encouragement from the Qur’an, feel they should hurry up the process of getting them there. To avoid criticism Muslims often claim these verses were only for a particular event in history and do not apply today. Christians, at times, are guilty of the same ploy when they find something in their scripture that they do not like. Some are known to say certain things only apply to the "apostolic age" or to the Jewish culture, etc.
One way of doing battle with the "infidels," or tolerated minorities under Islam within its borders has been to levy poll-taxes (jizyah) "obligatory alms" against them. These taxes are then used to finance jihad and Islamic expansion. It is beneficial to protect some people with a covenant Dhimma if they are offering to society something that Islam has use for.
