Medieval Christian polemicists treated Islam as closer to true faith than Judaism.

Evidence

The author tried to use the Qur’anic Christ to refute the Jewish faith, which, in its turn, he used to refute Islam. Thus it became particularly important that Islam recognises in Christ the Messias, the word of God, the son of the Virgin, and so on. These arguments belonged to that mediaeval tradition which saw the Jewish attitude as blasphemous, where that of Islam was not. Some Jewish books might need to be destroyed, where the Qur’an did not; Talmudic blasphemies against Christ constituted the reverse side of the Qur’anic praise of Him. — Norman Daniel, Islam and the West, 967
