I read it somewhere, i have googled but havent found any link as yet.
Why do people always go after literal meanings is beyond me.
Hazrat Muhammad (saw) is correct. The movement of jinns is called flying, they and other types are even called " hawai makhlook"(flying creation). But they dont fly like having wings like planes and birds, they TELEPORT. and thats referred to as flying.
Now, why would Koran/sunnah contain anything that helps in doing black magic and harming people.
Its a type of black magic technique, just like a technique used to do black magic on Hazrat Muhammad (saw)
