Imâm Sâlih bin Fawzân al-Fawzân
Question: Are amulets major or minor Shirk?
Answer: Depends on the intention; if a person believes that the amulet in itself protects and benefits, it is a matter of major Shirk. And if he believes that it’s only the cause while Allâh is The One who heals, that is minor Shirk – which, however, leads to major Shirk.
