If they oppress others with them, then they will be held responsible for it https://aboutislam.net/counseling/ask-about-islam/trying-to-understand-the-qareen/ 3-Their powers Allah has given jinn powers that he has not given to humans. Allah has told us about some of their powers such as the ability to move and travel quickly. One of the jinn guaranteed to Prophet Sulayman (Solomon, peace and blessings be upon him) that he would bring the throne of the Queen of Yemen to Jerusalem in a moment, faster than the time needed for someone to get up from where he was sitting. Allah Almighty says:“A stalwart of the Jinn said: I will bring it thee before thou canst rise from thy place. Lo! I verily am strong and trusty for such work. One with whom was knowledge of the Scripture said: I will bring it thee before thy gaze returneth unto thee. And when he saw it set in his presence, (Solomon said) This is of the bounty of my Lord. That He may try me whether I give thanks or am ungrateful. Whosoever giveth thanks he only giveth thanks for (the good of) his own soul: and whosoever is ungrateful (is ungrateful only to his own soul’s hurt). For lo! My Lord is Absolute in independence, Bountiful.”(An-Naml: 39-40) 4-is it possible for qareen to become visible to the eye? It is possible that the jinn can manifest itself in different forms, this is something unequivocal as about specifically the qareen (assigned to every individual) then we don't have an answer, though there's the saying that we can see it in our dreams in different forms like lion, snake,dog Allah knows best 5-how the qareen influences our thoughts? most Jinns that are companions to humans are evil and they try to lead us far away from Allah and straight to hell. That inner voice that we all have that coaxes us to look at something forbidden or to commit some evil action is actually the companion Jinn. All Muslims must adhere to the Quran and Sunnah and ignore their companion Jinn by enjoining what is good and forbidding what is evil. Allah almighty says in the Holy Quran: “His companion (Qareen) will say: "Our Lord! I did not push him to transgress, (in disbelief, oppression, and evil deeds) but he was himself in error far astray.” Allah will say: "Dispute not in front of me, I had already, in advance, sent you the threat. The sentence that comes from me cannot be changed, and I am not unjust (to the least) to the slaves." (50:27-29) The Jinns are very real beings and they are a part of our World. They do have an edge over us as they are invisible to us and can hurt us by Allah’s leave. 6-can you change it's behaviour? One opinion is that the qarin, being a jinn-type creature, if not guided by his human companion on the right path, becomes a shaytan by the command of God. The companion will be what its guide is or more than what the guide is However the second opinion is that the Qareen is evil and having one’s Qareen become a Muslim was something that was unique to Muhammad. With regard to the words of Muhammad,  In another hadith, the Prophet (peace and blessings be upon him) tells us that a demon is assigned to every human being:“There is no one among you but a comrade from among the jinn is assigned to him.”They (the Companions present in that occasion) said: “Even you, O Messenger of Allah?” He said:“Even me, but Allah granted me victory over him and he became Muslim (or: and I am safe from him), so he only enjoins me to do that which is good.” 7-protection from the qareen Because the Jinn can see us while we cannot see them, the Prophet Muhammad taught us many ways to protect ourselves from their harm, such as seeking refuge in Allah (God) from the accursed Satan, reciting chapters 113 and 114 of the Holy Quran, and reciting the words taught by God in the Quran: “Say: ‘My Lord! I seek refuge with You from the whisperings (suggestions) of Satan (devils). And I seek refuge with You, my Lord, lest they may attend (or come near) me.’” (Quran 23:97-98) Saying Bismillah (in the Name of Allah (God)) before entering one’s home, before eating or drinking, and before having intercourse will also keep Satan from entering the house or partaking with a person in his food, drink and sexual activity. Similarly, mentioning the name of Allah before entering the toilet or taking off one’s clothes will prevent the Jinn from seeing a person’s private parts or harming him, as the Prophet said.  Strength of faith and religion in general will also prevent the Jinn from harming a person. 8-jinn possession: between facts and illusions A Muslim has to believe in the jinn. They are mentioned in the Qur’an and Hadith. In many instances, they share with us many of our roles and actions. However, it is noticeable nowadays that many people, when they feel anything wrong with themselves, interpret that as a matter of possession by jinn. In fact, many of them will change their mind after they go to a doctor who checks up to find out that the person is diagnosed to have some physical or psychological problem. Every Muslim is to believe firmly that no one, however great his powers may be, can benefit or harm him unless Allah wills it. Then a Muslim’s best cure, protection, and immunity against the harm of jinn is by practicing Islam, reading the Qur’an and making frequent dhikr and du`a’. “There are some facts and some illusions connected to the issue of jinn possession, and among most people nowadays the illusions outweigh the facts. There is agreement among Sunni Muslims the jinn can dwell in the bodies of humans, but that does not mean that everyone who has epilepsy is possessed by the jinn, because epilepsy may have physical causes. The pains that many people feel in their bodies cannot be ascribed for certain to the actions of the jinn, rather they may be illusions or something imaginary. So a Muslim should not pay any attention to the whispers of the Satan that make he/she think that he/she has done this and that. This is one of the ways in which the Satan deceives the Muslim and makes him/her think that he can control him/her, and that he has powers that in fact he does not possess. This may lead to bad consequences as has happened to many people. A Muslim has to keep on treating himself with ruqyah, for the Book of Allah is available to him/her. One should recite from it and treat him/herself with ruqyah. Whether one is possessed or not, he/she will undoubtedly benefit from this reading and ruqyah. A Muslim has to seek the help of Allah and pray to Him and beseech Him to prevent the plots of the devils among mankind and the jinn from harming him/her. Man is always in need of his Lord, and Allah is Able to rid one of these thoughts, illusions and facts that are harming him/her.” Shedding more light on the protection against and the immunity from the harm of jinn, we’d add the following: “Because jinn can see us while we cannot see them, the Prophet (peace and blessings be upon him) taught us many ways to protect ourselves from their harm. They are seeking refuge of Allah from the accursed shaytan, reciting surat Al-Falaq and surat An-Nas, and reciting the words taught by Allah in the Qur’an. Allah Almighty says, “And say: My Lord! I seek refuge in Thee from suggestions of the evil ones. And I seek refuge in Thee, my Lord, lest they be present with me.” (Al-Mu’minun: 97-98) 9-when you sleep can your qareen go anywhere? Some hearsay indicated that when you sleep your qareen wander around you in the room and can't be far from you more than 800 meters, but nothing for sure. All I can tell you that (In Many occasions I meet someone for the first time but they assure me that they saw me before in somewhere I have never visited before!)thanks to Allah I mostly go out with family or friends or I would go crazy  So my qareen if you do that stop it . 10-where does your ‘qareen’ go after our death? When a human dies normal death his qareen becomes free because his job is done by the death of the human who it was assigned to.where it goes after the human dies nobody knows.
