Is any contact between Jinn and human beings possible? (It is heard that Jinn and Ins have marital relation). Can Jinn attack human beings and cause physical injury? It is believed that Jinn enters the body of human beings, and the person acts as if he is the Jinn who orders innocent people for financial purposes. Your comment please.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

1) If we suppose that a human being can marry a female Jinni, this is unlawful in the Sharee’ah, for the following Divine statements in the Quran; Allah Says (what means):

• {And Allah has made for you from yourselves mates and has made for you from your mates sons and grandchildren and has provided for you from the good things.} [Quran 16:72]

• {And among His Signs is this, that He created for you wives from among yourselves…} [Quran 30:21]

The interpreters of the Quran said while explaining the above two verses: “He (Allah) has created spouses for you from among yourselves, means from your kind, genus and innate character. Imam As-Suyooti said in al-Ashbaah wan-Nathaa-ir book while deducing from the above two verses: “If one says: What is your opinion concerning such a marriage [between a human and Jinn]? I say: I believe it is unlawful.” Then, he added: “It was reported that Al-Hasan Al-Basri, Qataadah, Al-Haakam, Ibn 'Uyaynah, and Ishaaq Ibn Rahawayh prohibited it; i.e., the marriage between a human being and a female Jinni.”

Al-Jammal As-Sijistaani, a Hanafi scholar, in his book Muniyat al-Mughni ‘an al-Fatwa al-Sirajiyah said: “Marriage between a human being and a Jinni is unlawful due to the difference in species.” Al-Jammal mentioned also “other reasons to such a prohibition since marriage is enacted for the purposes of (1) familiarity, (2) repose, (3) intimacy, and (4) cordiality that are lacking in case of marriage between a human being and Jinni.”

In addition, 'there is no evidence in the Sharee’ah that authorizes such a marriage. Allah Says (what means): {… then marry (other) women of your choice…} [Quran 4:3]

'Here, the word "Women" indicates the human females in particular. This means that it is unlawful to marry other females, since the basic principle, refers to the prohibition of delighting in pudenda (the sexual parts) until an evidence is stated for legality.'

'In the same vein, Islam prevents a free man to marry a female slave since her children will be harmed with being slaves. Without a doubt, harm that will befall a child from a female Jinni is worse than the harm of slavery, which is possible to eliminate. Also, such a child will be with a blemish from the form and character of the Jinn due to his/her relations and mixing with them (Jinn).'

Indeed, marrying a female demon has been prohibited for what is previously stated. It is also prohibited lest some pregnant woman may claim that she is pregnant from her Jinni husband. Such a state will increase moral corruption.

Al-Mawardi said concerning marriage between human beings and Jinn: “Minds disapprove such a marriage since there is a difference between the two species; i.e., mankind and Jinn. They also have different natures; a human being is corporeal while a Jinni is incorporeal; the first is created from sounding clay like the clay of pottery while the latter is created from fire free of smoke. Thus, intermingling in such a case of difference is repulsed and sexual reproduction is barred.”

Finally, we say that if the marriage between a human being and a female demon is possible, it is still unlikely, as it will result in so many blights since the female Jinni can appear in many shapes. Then, how can one trust that this female is his wife? Maybe she is not. To be valid, marriage needs a guardian and two just witnesses, and the woman should be free from the Sharee’ah prohibitions (like ‘Iddah or Ihram state). Perhaps it is impossible to meet all the above-stated conditions due to the difference in nature of the two species; i.e., mankind and Jinn.

2) You ought to know that the devil's cunning/deceit is weak and he cannot harm a believer who takes shelter with Allah.
Allah Says (what means):

• {Indeed, the plot of Satan has ever been weak.} [Quran 4:76]

• {Indeed, My servants - no authority will you have over them, except those who follow you of the deviators.} [Quran 15:42]

Thus, the devil has no dominant influence except over those whose faith is weak, those who are shunning Allah's remembrance, and those who indulge in evil misdeeds. So, the devil will share the house with the above-mentioned people and may encroach upon them, in their bodies and property.

Thus, a Muslim has to protect himself/herself with Allah's remembrance such as: (1) reciting Soorah Al-Baqarah (the Cow) in the house keeps the devil away, (2) mentioning Allah's Name when eating, drinking and entering the home denies the devil access to food and an overnight stay, and (3) mentioning Allah's Name just at the moment of having sex with one's wife prevents the devil from having any form of enjoyment.

The devil, in fact, takes up lodgings in places of disobedience. So, one has to purify one's house of prohibitions such as statues, musical instruments, singing, dog and pictures, which prevent angels from entering the house.

3) As for a Jinni entering into a human being, we say that such is a known accomplished fact. Allah Says (what means): {Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity.} [Quran 2:275]

The devil may harm a human being down, with Allah’s permission, by acts of the magician himself, or due to the human being injustice and aggression to gain some worldly benefit or desire.

It is forbidden to obey the devil's orders concerning slaughtering and so on. However, the legitimate method for treating epilepsy is through Ruqyah; i.e., Quranic recitations and prophetic supplications.
