Point 1: The spirit appearing to Mohammed was not properly tested

Mohammed was visited by a spirt when praying in a cave in 610 A.D., who commanded him to read 3 times. Mohammed couldn’t read and instead recited. Mohammed is rightly afraid of the spirit and Kadija, his wife decides to test the spirt, as seen in the book “The Life of the Prophet' by Ibn Hisham. And how did Mohammed’s wife test the spirit ? By asking it to sit on her knees and lap. This is not how you test a spirit to determine if it is evil, as urged by the Bible. See verse in point 3.

Point 2: Lucifer (Satan) can appear as an (angel) spirit of light and mislead you

2 Corinthians 11:14

“And no wonder, for even Satan disguises himself as an angel of light.”

Galatians 1:8

“But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.”

Colossians 2:8

“See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.”

Point 3: The spirt appearing to Mohammed was against God

1 John 4

“Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.”

Qur’an:

Sura 9:30

“Christians say, “The Messiah is the son of Allah.” Such are their baseless assertions, only parroting the words of earlier disbelievers. May Allah condemn them.”

Conclusion: Islam comes from the spirit of the Anti-Christ.
