Perhaps you are not aware of what the Qur’an says about Jesus. That which is taught, one can learn in Surah 2 (a “Surah” will correspond to a “Book,” or perhaps a “chapter” in the Bible). For instance, in Surah 2:87, one learns that Jesus was mortal. One won’t read that in the verse, but Islamic commentators will declare it. “Maulana gives some instruction concerning the Qur’an’s use of the Arabic word for Jesus (Īsā), followed by the epithet ‘son of Mary,’ ‘to show that he was a mortal like other prophets of God’” (footnote 128 in Maulana Muhammad Ali’s translation and commentary on the Qur’an; from RT’s personal study notes of the Qur’an).
The significance of this is in relation to what the Scriptures teach relative to Jesus. Note what charge the apostle Paul gave to Timothy, a young preacher he left in Ephesus: I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who in his testimony before Pontius Pilate made the good confession, to keep the commandment unstained and free from reproach until the appearing of our Lord Jesus Christ, which he will display at the proper time–he who is the blessed and only Sovereign, the King of kings and Lord of lords, who alone has immortality, who dwells in unapproachable light, whom no one has ever seen or can see. To him be honor and eternal dominion. Amen (1 Timothy 6:13-16, ESV).
One does not need any other reason to oppose Islam, though there are untold numbers more!
