Hi gad_rania and welcome to the forum. I've skimmed through that article and it makes some very interesting points. You mention jinn, as does the article, and I've recently learned about jinn. Reiki in itself does not use spirits. In the mentioning of using God as your energy, many practitioners do exactly this. I'm not really sure why you would want to reverse your attunement, because in Reiki there is no harm. I know a few Reiki practitioners and masters who are Muslim and they are very successful and happy doing the Reiki. It's all in the intentions. For example, anytime I give Reiki, I ask permission first, then I ask the universe for balance. that's all. Some practitioners are more into the symbols, other rituals, or closing techniques, but the teacher (master) that I learned from said that this is all up to you. I think you would be best to find a Reiki Master who is Muuslim, and, if you can, from your own background. I'm only saying this because the place that I learned about Jinn was on a travel show, and the traveller was in Afghanistan. BUT, what was interesting as well, was that he was told to go to a specific town and to meet a healer. The healer was an older man who used snakes, and would tell the patient what was wrong with him and what he had to do to get better. So, obviously the healer is not doing anything wrong, and in Afghanistan they believe in Jinns, and they give advice on how to get rid of them. So thre were a few things that the healer had told the traveller was wrong, gave him advice on what to do to remedy things, and the traveller said that much of what the healer said was true. I really hope this helps you. I'm certified in Level 2 of Reiki, and I often come across or hear about Reiki practitioners or masters saying really crazy things, or insisting that their way is the only right way. Take a look through the Reiki subforum, and you'll find a lot of stories, but also lots of good advice.
