When I read the Quran most of the time I shake a lot and move my head along with the Quran, my brother laughs and tells me that I look like when the Jews read the Torah in the Western Wall, I find it very easy to concentrate when I do this, is this permissible to do?
This is permissible to do. If this helps you read it and you can concentrate better, that’s fine you can do that. It’s not haram. Yes, if doing that in a place will be seen by people as mimicking the Jews, then avoid doing it.
