both of you are exactly correct.
as for the “Demon” part, if you read the Sira, in addition to ahadith and Quran, it is clear, that the “angel of light” Mohammad first saw in the cave, is the Prince of Lies himself.
in ANY encounter with angels in the Bible, the human is told “be not afraid”. Yet the angel in the cave, TERRIFIED Mohammad, and choked him, and shook him!
Jesus himself, warned that Satan could still appear as an angel of light.
other things, show that Islam IS the religion of Satan.
for example, Psalms says Satan doesn’t like music.
in Islam, music is haram.
in the Bible, old and new testaments, marriage is a special sacrament.
Ephesians says the husband should care for his wife, as Jesus loves his church!!!
in Islam, a woman is property, a field for the man to tilth at will.
The Bible warns those who hurt childen. Mohammad is told he can rape captives, and have sex with a 9 year old child!
Pretty much the way I look at it, too. Mohammed the demon-possessed pedophile and his demonic master created a religion to turn bandits into a conquering horde.
