As salamu allaiqum,
After the death of a person his soul sometimes visits its relatives in their dreams. Sometimes the soul is also visible when the relative is an awake. At times, the relatives may only hear the voice of the deceased person but since this is a supernatural phenomenon, they are unable to comprehend it.
Those people who die an unnatural death like getting killed in an accident or getting murdered etc plead before Allah that they he should destroy the life of their murderers just like he or she had destroyed their life. Some of these evil spirits return to the place of their death with vengeance. They try to scare their murderers in different ways. Sometimes the enemies of such vindictive evil souls hear frightening sounds while sleeping like the sound of someone’s crying or breaking of buttons or pelting of stones. In other words their lives become hell.
Research has confirmed that the souls of the people who get buried after death without the namaz at the funeral, wander in this world. The souls of such people who commit suicide or were murdered and the souls of the illegitimate children of some women, whom she may bury furtively, to save herself from ignominy etc, do not get a decent funeral with the compulsory namaz. Such souls can cause trouble to the people around and make their lives miserable. The magicians try to use such souls for their own selfish motives by capturing them from deserted places or graveyards by chanting some mantras.
One may have a feeling as though someone is following a person or a white shadow is trailing behind a person.
In some cases such a person who is being targeted by such evil souls feels unwell and has a headache almost constantly.
The victim keeps getting negative and evil thoughts all the time.
The brain does not function normally and one may see a white apparition which disappears all of a sudden.
Sometimes the victim feels as if he has seen something but when he gazes at it intently, he sees nothing.
The victim may feel at times as though someone has called him but actually no one may have called him at all.
The victim may feel petrified at times
In such case it is advisable to hire a proficient amil so that even if the evil soul becomes more vicious, the victim or his family remains unaffected since the amil may be better equipped to deal with such an evil soul but the victim may not be able to understand what is happening to him at all. So it is better to pay a little amount to an amil and hire him to do this task so that even if the evil soul gets agitated, it may try to take revenge upon the amil and not the victim.
If an amil is not available then the following amal should be followed:
Till 21 days the victim should read Ayatal Kursi 111 times in the morning and in the evening.Surah Naas should also be read 111 times both in the morning and the evening. Before retiring at night the victim should read the four Quls and Ayatal Kursi 11 times each. Inshallah, the evil spirit may be compelled to leave the victim by the power of this amal.
This verse should be written or printed and after reading it 111 times, the air should be blown over it and it should be worn around the neck as a taweez.
Remember me in your prayers
