Muhammad's contacts with the Jewish and Christian scholars were very limited. The most prominent Christian known to him was an old blind man called Waraqa ibn-Naufal who was a relative of the Prophet's first wife Khadija (ra). Although of Arab descent, he was a convert to Christianity and was very well versed with the New Testament. The Prophet (pbuh) only met him twice, first when Waraqa was worshipping at the Ka'aba (before the Prophetic mission) and he kissed the Prophet's forehead affectionately.
The second occasion was when the Prophet (pbuh) went to meet Waraqa accompanied by his wife Khadija (ra) after receiving the first revelation. Waraqa died three years later and the revelation continued for about 23 years [in total the revelation took about 23 years]. It is therefore ridiculous to assume that Waraqa was the source of the contents of the Quran, as he died at the very beginning of the Prophet-hood [Bracketing mine] - Quotes in red from, Islam: Silencing the Critics, Zia Sheikh, 2nd Edition, 2012
Scientific facts in the Quran:
Jesus taught people to do the Will of God (according to Mark 3:35) in order to become his brothers, mothers or sisters. A Muslim means one who submits to the Will of God. Do you want to become a brother of Jesus? If yes, become a Muslim. Now is the time.
