It’s a political system.
Yes, it’s been described as a politico-religious cult. I find nothing spiritual about it. There is no “Do unto others as you would have them do unto you”. It’s closer to the Luciferian philosophy of “Do to others before they do to you”. The relationship between Allah and man is more like a slave owner to his slaves, rather than a heavenly father as Jesus described it. There is no effort required to be a Muslim more than just accepting a flawed man, Muhammed, as God’s prophet. Christianity requires a transformation, as Jesus put it, being reborn. Reborn into a new spirituality, while Islam is still rooted in this worldly system, and all its corruption. Islam attracts those who want to keep their old ways of getting what you want by force. It appeals to the animal side of people, not the spiritual side.
