can jinn enter to human body??

'In the book written by Wahid Ibn Abdessalam, when he was performing an exorcism, he mentions: A man brought his wife for treatment and said that his wife hated him very much and felt relaxed at home, during his absence. When I asked few questions, it appeared to me, from the symptoms she had that she suffered from sihr of separation. After listening to the ruqya [reciting Surah’s of Quran to provoke the jinn in a possessed person], a Jinn spoke in her person. Here is a summary of our dialogue:
Q: “What is your name?”
A: “I will not tell you my name”
Q: “What is your religion?”
A: “Islam”
Q: “Do you think it is lawful for a Muslim to torture a Muslim?”
A: “I love her, and I am not torturing her All I want is that her husband should keep away from her,”
Q: “You want to separate them, don’t you?”
A: “Yes”
Q: “You cannot do that Get out of her, for the sake of Allah’s obedience,”
A: “No, I love her,”
Q: “But she hates you”
A: “No, she loves me,”
Q: “You are a liar, She hates you and that is why she has come here to get you out of her body,”
A: “I will not get out”
Q: “Then, I will burn you with the Qur’an (by reciting verses) ,”

I recited some verses over her and he screamed,
Q: “Will you get out now?”
A: “Yes, but conditionally”
Q: “What is your condition?”
A: ‘To get out of her and to enter in your body,”
Q: “All right, get out of her and enter into my body if you can”

The Jinn waited for a moment then cried,
Q: “Why are you crying?”
A: “No Jinn can enter into your body today,”
Q: “Why?”
A: “Because this morning, you said:
[La ilaha illallahu, wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, wa huwa 'ala kulli shai'in qadir']

{There is no true god except Allah. He is One and He has no partner with Him; His is the sovereignty and His is the praise, and He is able to do all things} 100 times.

And the Prophet (peace be upon him) was truthful when he said: “Whosoever says: [La ilaha illallahu, wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, wa huwa 'ala kulli shai'in qadir'] 100 times a day, will have a reward equal to the manumission of 10 slaves, will have ten good deeds added to and ten bad deeds erased from his register, and will be protected by this supplication the Satan throughout the day until the evening, No one is better than he who says this supplication except a man who says more.”'
