Is the Video below Authentic? I dont know. But I tell you what, I have clearly seen shirk written inside these things and asking for help from others and not Allah. When am asked to take one of these amulets for my wife or kids, I always refuse but take it to see what it is filled with. Sometimes I get asked why I dont believe in them, My answer is simple, I dont need to expalin. However I tell the person trying to pass it on to me to open it and read it. If it is pure Islamic, then fine, otherswise it gets burnt.
The main part of the video comes towards the end. I'ts only 3 minutes, watch it.
