Luther located the final Antichrist inside the Church, not in Islam.

Evidence

Luther wrote as if he were a man in the twilight of Christendom before the long night, and, as he looked into the future, he asked whether Mahomet and his followers were the final Antichrist. Like Joachim of Fiore, he answered No. Islam was too gross and irrational for this mighty role: the true and final, subtle and insidious Antichrist must come from within the Church; he was none other than the Pope himself. This had been the picture also of Joachim and of much late medieval apocalyptic, though Luther added thereto his own theological hostility. For him and them, Christendom was caught in the grip of an external and an even more formidable internal enemy. — R. W. Southern, Western Views of Islam in the Middle…, 572
