Anyone involved in these kinds of "magic" activities and doing the so called "عمل" involving magic should be punished with the severest punishment, as they are playing with lives of common man who falls to their bait.
But again why not take the thing from the root. The root cause of the problem is the government and their appointed "religious clerics" who bend and twist the religion to facilitate what their masters want. 64 years on and Islam in it's true form is still not implemented yet in the "Islamic" republic of Pakistan.
If these so called magicians really have these abilities and powers, why don't they use to kill corrupt politicians of Pakistan who are playing havoc in Pakistan.
