Yes, magic and effect from a jin is a truth and it can take place:
وھو علم یستفاد منہ حصول ملکۃ نفسانیۃ یقتدر بھا علی أفعال غریبۃ لأسباب خفیۃ (شامي)
So, in case of magic the hidden causes affect a person as in other things the apparent causes produce effect. By this, no one can be strongest person of the world.
