You need to understand certain points before doing haziraat. First of all you should see if the victim of magic is strong enough to bear the haziraat process. If the victim is old and feeble or weak then haziraat should be avoided. If haziraat is performed on a weak person then it can affect his health.
Secondly, only those who have a certain amount of knowledge of amalaat should go ahead and summon the jinnat. Otherwise, if the jin appears somehow and you do not know how to handle him then he will at once understand your weakness and he will wreck havoc. Instead of helping the victim you may end up aggravating his miseries. If you are unable to control the jinnat after haziraat then he will throw a lot of weight around. He will leave no stone unturned in making the victim and his family miserable. He will get a chance to take revenge upon the victim for having the guts to make him appear before an amil. If the amil is not powerful enough to do a haziraat then he should avoid it. Otherwise there will be a nasty situation of the jinnat becoming unbridled and wrecking havoc on the victim. The amil will end up getting cursed by the victim and his family for all his life.
Therefore you should first prepare yourself fully before you embark on the program of haziraat.
