Dear Brother NMH1977

,
I would like to clarify. For the person who goes to the one who cooperates with the jinn to find out where is lost object is, I did not say that his prayers would not be answered. His prayer is valid, however, he will not get reward for the prayer. There is a difference between having a valid prayer (that is, fulfilling the integrals of the obligation of prayer) and fulfilling the conditions to get reward for your prayer.
There are conditions that one must meet in order to get reward for their prayer such as having at least a moment of fear of Allah. Many times, people pray but do not think about fearing Allah and the torture in the hereafter, rather, they think about what to cook, money, business, the kids. etc.
Second of all, there is no need to be confused brother.
There are people who get help from the jinn. The jinn do assist others in many ways such as providing information about lost objects or about someone's past.
IT IS HARAM to do so.
Not everyone, however, fears Allah subhanahu wa ta^ala. People write books about black majic or about how to get assistance from the Jinn because most of the time it brings them wealth in this life.
An example is David Copperfield. When he flew, it was because the Jinn were carrying him. The jinn are invisible to most people. How much money did David Copperfield earn from ticket revenues???
It is shirk (associating a partner to Allah) if the person believes that the Jinn has the power to create. It is also shirk if someone worships the Jinn. Most of the time, the people that cooperate with the Jinn commit blaphemy because the jinn ask for something in exchange such as writing a verse of the Qur'an in filth (blood, urine. etc.) Satan wants people to commit sins and to commit blasphemy.
So we do believe that there are people who get assistance from the jinn. We
DO NOT believe that the jinn are the creators or that they are attributed with Power like Allah.
The creations have power, but not like the Power of Allah. The Power of Allah is Eternal and Everlasting. Allah has the power to do whatever he wills. The limited power the creations have is created by Allah.
We have the power to eat, drink, go to school, work, etc. Likewise, the jinn have the power to lift people, reveal information, hurt people. etc.
A scholar named An-Nasafiyy said: "If a person hit a glass with a stone, and broke it, then the acts of hitting and breaking and the state of being broken were created by Allah". The slave only acquires the act. Allah is the only one who creates (i.e. bringing the creations from non-existence into existence).
I hope it has become clearer for you brother...if not, please continue to ask.
