Christian-Muslim controversy necessarily centers on their fixed points of doctrinal disagreement

Evidence

Islam and Christianity are concerned apparently with much the same themes; fundamentally, they differ about the means that God has used to reveal Himself. They differ about the nature of revelation itself; about the nature of the revelation which they agree was made by Christ; and about the nature of the revelation which only Muslims believe was made through Muhammad. The field of disagreement involves such questions as the character of prophethood, of the Trinity of Persons in the Godhead, and of the Incarnation. — Norman Daniel, Islam and the West, 38 (#expands, via linked claim)

Peter attempts to prove that Muhammad is not a prophet, for a prophet by definition foresees the future, whereas Muhammad did not. Here Peter is unaware that the Muslim concept of rasûl is quite different from the Christian notion of propheta: the latter by definition predicts future events, while in Islam a rasûl is a messenger of God, bringing the message that man must submit to God’s will. In showing that Muhammad does not correspond to Peter’s notion of prophethood, he is scoring a point that would carry little weight with a Muslim audience. — John V. Tolan, Saracens, 864 (#expands, via linked claim)

The theoretic assessment remains clear. Islam was a falling away from the truth which the Christian Church preserves; and in this way was paralleled the Islamic concept of Christianity as a falling short from the truth preserved in Islam. On both sides it was the extent of disagreement, not of shared beliefs, on which men concentrated their attention. — Norman Daniel, Islam and the West, 1080 (#corroborates, via linked claim)
