هل يصبح المسلم كافراً إذا قام بحركات عبادة الشيطان دون قصد؟

If the movements are not exclusive to disbelievers and do not resemble anything forbidden, then there is no sin upon the one who performs them. However, if they are exclusive to disbelievers and a person performs them merely for play, not out of love or glorification, then they have committed something forbidden, but they are not considered a disbeliever by doing so.
