For context, I am a sunni who wants to become a shia, but something has always lingering in my head. I was invited to go to a shia masjid for ashura. I went there, and had an interesting day. The event that made me doubt shia islam, is when I am leaving. A man gives me a hand shaped thing with an evil eye on it. I tell him that the evil eye is shirk, but he said that it is a different type. Ever since then, it has been lingering to me, the hand shaped thing thing, which I found out was a hamza hand, is used by Jess for protection, and evil eye is shirk since it is believed to protect you. The shia talismans, or the thing you add on the Alam flags, those also gave me concerns, as that can be seen as shirk. I need a proper person, or a holy shia muslim to please help me answer this: if allah declared amulets, and talismans as shirk, why do shia Muslims do it, also, even I it has Islamic verses, can't you just read a dua to protect yourself from evil?
