evil eye - Jinn possession and the rulings on jinn possession

Can jinn possess humans? And if this is possible, then how will the
person be able to account for their actions,whilst they were
possessed, on the Day of Judgement?.
Praise be to Allaah.
Firstly:
Yes, it is possible for jinn to possess humans. Allaah says in His
Book (Interpretation of the meaning):
"Those who eat Ribaa [usury] will not stand (on the Day of
Resurrection) except likethe standing of a person beaten by Shaytaan
(Satan) leading him to insanity"
[al-Baqarah 2:275]

Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said:
The fact that a jinni may enter the body of a human is proven by the
consensus of the imams of Ahl al-Sunnah wa'l-Jamaa'ah. Allaah says
(interpretation of the meaning):
"Those who eat Ribaa [usury] will not stand (on the Day of
Resurrection) except likethe standing of a person beaten by Shaytaan
(Satan) leading him to insanity"
[al-Baqarah 2:275]
and in al-Saheeh it is narrated from the Prophet (peace and blessings
of Allaah be upon him) that "The shaytaan flows through the son of
Adam like blood." End quote.
Majmoo' al-Fataawa (24/276, 277)
Secondly:
Possession is a kind of sickness. If a person whohas this sickness is
rational, then he has the choice and he will be brought to account for
his words and actions. But if this sickness has overwhelmed him to
thepoint that he has lost his mind and free will, then he is like one
who is insane and is not accountable. Hence in Arabic the word mass
(possession) is used to refer to junoon (insanity). See Lisaan
al-'Arab (6/217). But if hecommits an act of aggression against
another when he is insane and destroys his property, for example, then
he must pay compensation for that.
See: Zaad al-Ma'aad (4/66-71)
It says in al-Mawsoo'ah al-Fiqhiyyah (16/106):
The fuqaha' are unanimously agreed that insanity is like
unconsciousness and sleep, rather it is more severe in the loss of
free will, and it makes whatever he says invalid. For the one who is
sleeping, all his verbal statements, such as divorce, becoming Muslim,
turning apostate, selling, buying,etc, are invalid. So it is more
appropriate that such statements be invalid in the case of insanity,
because the insane person has no power of reasoning or discernment.
They quoted as evidence for that the words of the Prophet (peace and
blessings of Allaah be upon him): "The Pen has been raised from three:
the sleeper until he awakens, the child until he reaches maturity and
the insane person until he comes back to his senses." Narrated by the
authors of Sunan with a saheeh isnaad. The sameapplies to all verbal
statements because of the potential for harm. End quote.
In (16/107) it says:
With regard to the rightsof people such as compensation and the like:
these are not waived, because he is not accountable for them, rather
his guardian is responsible for paying financial duesfrom the wealth
of the insane person. If he commits some crimes, heis accountable for
them financially but not physically. If he destroys a person's
property when he is in a state of insanity, compensation must be paid,
but if he kills someone there is noqisaas (retaliation), but the diyah
must be paid.
And Allaah knows best.
