This is a GREAT question. Just because one evil speaks out against another evil doesn't mean they're not both evil. The Nazis may condemn the rapists, but that doesn't justify either of them.
Two evil people can fight against each other for power. In that respect, they're not getting rid of evil, just replacing it with another evil.
Here Jesus was actually getting rid of the evil (casting out demons). The accusation against him was that by the prince of demons he was casting out demons. This is obviously a different situation than anything that applies to Muhammad. Muhammad can still be accused (by Christians) of being misled by Satan because he used his armies to kill Christians and to conquer territories held and governed by Christians. If we want to say it this way, Satan could have been at work in Muhammad not to work against Satan, but to work against God.
But your question is how could Muhammad been in league with Satan if he claimed, as Christians do, that Satan is the enemy? I think the answer might lie in the perception that Muhammad didn't realize he was a tool in Satan's hand. Muhammad regarded himself as an ambassador of the true God (and therefore an enemy of Satan), but Christians would say Muhammad was deluded and wrong about that—that he was truly an agent of Satan posing as a prophet of God, and he used that position to work against God (without necessarily realizing it). It's one of the strategies of the deviousness of Satan.
It is the perception of Christians that Islam is the greatest of all Christian cults. Muhammad took the writings of the Bible, changed them to suit his preferences, made Jesus not divine, made sure people were told not to read the originals ("Oh, the Bible is holy, but it's so corrupted you can't really give it any value"), and replaced it all with his own "holy book." The Mormons and Jehovah Witnesses did the same thing, but on a much smaller and non-violent scale.
Have I understood your question correctly?
