Ted, if you are interested in this topic, there is a whole book on the subject:

Samuel M. Zwemer, chapter vi, “Mohammedan Ideas of the Trinity”, The Moslem Doctrine of God, (New York: American Tract Society, 1905).

I don't have space to discuss all the details. For example the Qur’anic passages about Jesus are possibly focused on the medieval Catholic-Byzantium worship of intercessory saints, because as Zwemer points out, the Qur’an is actually focused on those who link Jesus’ divinity to that of the Virgin Mary
