Islam is a syncretist cult. They quote Scripture and talk about Jesus whenever it’s convenient for them to do so, and this was one of the things that Mohammed began to include more and more in his “message” to make his military victories sit a little easier with the mostly Christian conquered peoples.
But their Jesus is entirely different from the Christian Jesus, and fits in perfectly well with Mohammed’s insane hallucinations. Don’t be fooled. Many Middle Eastern Christians were fooled by it, since the ME at that time was a hotbed of heretical forms of Christianity not in union with Rome, and many of the residents obviously regarded this as yet another one.
Farrakhan has reconciled with Islam (the more orthodox, non-prison version) and now he is trying to do the same with a race-baiting “Catholic” priest whose bishop is too timid to discipline him or even oppose him.
At least now, thanks to the internet, this insane cult called Islam is being exposed more and more for what it truly is. It is not suprising as you have posted that the ME and North Africa fell to the Mohammidians because of the sad divisions that even back in the 7th century was troubling the Christians. This is a sad reminder of when there is divisions in the Body of Christ, it opens up the way for crazy cults to come right on in with their false prophets.
