I have one very simple question about black magic. I know that it exists, but I have heard from somewhere that whoever commits in the act of black magic is a disbeliever. Period, there is no 2 opinions about it. I would like to know is such a thing true? Is it supported by the Quran or the authentic Hadiths that whoever commits black magic is a disbeliever. On top of that if it is the case then why is it listed as a sin of its own and listed as a sin below murder in the 70 major sins. Shouldn't it just be called shirk or kufr for that matter? Thanks.
