There are two kinds of people. Weak minded and strong minded. This could also mean people weak and strong in faith. People of weak mind and faith are the ones who black magic will work, and who will easily be hypnotized and easily fall into traps.
Lets take the most common form of the alleged black magic trait: breaking up marriages (dispute among couples etc), sudden change in mood for no apparent reasons and inability to perform well or normal in any task.
A person weak in faith will lose his faith in Allah (SWT) and increase his faith in magic, he HIMSELF is going to lead his life into unknown consequences (mostly bad since he will be guided by negative energy fueled by his thoughts).
A person strong in faith will take it as a test. He knows what ever is happening in his life, he ALONE is responsible, no one else in this world causes his life to fcuk up.
As for the ignorant people here to say not beliveing in black magic implies not believing in the word of god. Well let me tell you this yet again loud and clear: There is NO MENTION OF THE WORD 'BLACK MAGIC' in the Quran. The meaning of the arabic word is many, but revolves around this: "to make something of some form appear unreal". Some believe it to be magic, other believe it to be the art of illusion. Both mean the same thing. There is no mention of black or white so get this in your stupid tiny lame ignorant brain of yours.
Those who believe in black magic, it will effect them. Those who don't, it wont effect them. Its as simple as that.
And yet again, I will say this: if such a practice caused effective results, then put it on the terrorits, put it on the light and measure it emperically. Now why do you think this has not been done? because its simply not possible as it does not exist.
hey what happened like why did u made the nick of black magic?are u affected by black magic?
