Whoever hangs an amulet has committed Shirk (polytheism)

A group of people came to the Prophet (may Allah's peace and blessings be upon him) and they were ten. He accepted the pledge of allegiance to Islam and to follow him from nine of them and did not accept it from the tenth person. When he was asked about the reason behind that, he (may Allah's peace and blessings be upon him) said: He is wearing an amulet, beads or other things that are tied or hung to ward off the evil eye or harm.

So, the man put his hand in the place where the amulet was, cut it, and got rid of it, and the Prophet (may Allah's peace and blessings be upon him) then accepted his pledge and said by way of warning against amulets and clarifying its ruling: "Whoever hangs an amulet has committed Shirk."
