Wearing amulets or other items containing Qur’anic Ayahs is Haram (prohibited) according to the more correct of two opinions held by the scholars. If amulets contain things other than the Qur’an, it is even more prohibited. The levels of ruling on this differs according to the intention of the person; it can be major Shirk (major form of associating others in worship with Allah) if one thinks that they have an effect independent of Allah; and it can be minor Shirk, or a Bid‘ah (rejected innovation in religion), or a sin. In all cases, it is impermissible to make these things and you should not pray behind such persons who make them or wear them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
