Ruling on eating the slaughter of one who wears amulets

Question:
From Nigeria, this is a message sent by one of the listening brothers, Abu Bakr Ali Muhammad Ali. He says in his message: Is it permissible for a person to eat the slaughter of one who wears amulets?

Answer:
This requires a detailed explanation:
If it is known of the one who wears amulets that he associates partners with Allah, and he believes in the amulets that they benefit and harm apart from Allah, and he relies on them apart from Allah, or he believes in the dead and calls upon them, seeks their aid, and makes vows to them, or in trees and idols, or in the jinn and calls upon them and seeks their aid, then his slaughter is not eaten.
As for if he wears them as a custom, because he sees them as among the causes of benefit, and he does not believe that they are the ones who harm and benefit, and he does not engage in any of shirk (associating partners with Allah), then his slaughter is eaten; because wearing amulets is minor shirk (associating partners with Allah), yes.
