The Quran/Koran recognizes that Mary was a virgin but does not recognize Jesus as the Son of God nor the Trinity. The inscription on the Dome of the Rock, which predates the final compilation of the Koran, seems to also recognized Jesus as The Messiah, though not as the Son of God. It reads:
"O you People of the Book, overstep not bounds in your religion, and of God speak only the truth. The Messiah, Jesus, son of Mary, is only an apostle of God, and his Word which he conveyed unto Mary, and a Spirit proceeding from him. Believe therefore in God and his apostles, and say not Three. It will be better for you. God is only one God. Far be it from his glory that he should have a son."

I'm going to assume from that quote that the koran denies Jesus is the Son of God.
From the Holy Bible I John 2:22-23 says:
"Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.
Whoever denies the Son does not have the Father; the one who confesses the Son has the Father also."
