What does Islam say about the phenomenon of déjà vu? What should a person do if that happens to him?

Dear Brothers & Sisters,
As-Salaamu-Alaikum wa Rahmatullahi wa Barakatuh. (May Allah's Peace, Mercy and Blessings be upon all of you)
One of our brothers/sisters has asked this question:
Can you please tell if there is an Islamic explanation of Deja vu (seeing something and realizing that you have seen the exact same thing before). What should a person do when such a thing happens to him?

Praise be to Allah

Déjà vu is a French phrase meaning already seen. It refers to a person feeling that he has lived or seen before the situation he is currently experiencing.

Neurologists and psychologists differ concerning the explanation of this phenomenon.

Some them attribute it to an anomaly in the memory, having to do with connections between the nerves that are responsible for short-term memory and long-term memory.

Some of them attribute it to feelings or emotions being experienced in the present, that bring to mind details of some past events, which makes us feel that we have lived the present event before.

Some of them attribute it to information that we learned before, but we forgot it, then the brain retrieved it, so we imagine that we lived through the event twice.

However, many followers of certain religious beliefs or parapsychological schools of thought attribute the phenomenon of déjà vu to supernatural forces, or parapsychological interpretations, explaining it on the basis of ideas such as telepathy or hypnosis, or attributing it to ghosts or poltergeists, or other speculative interpretations for which there is no evidence.

You should understand that there is no Islamic explanation for this phenomenon, and it is not discussed in the Qur’an or Sunnah, or by any of the scholars of Islam, and it has no connection to any of the fundamental or basic teachings of Islam.

Regarding this matter, there is nothing except hypothesis or observation in the realms of experimental neurology, or speculation and claims made by followers of innovated or polytheistic religious beliefs that have nothing to do with Islam.

If this happens to you, all you have to do is reflect on the great blessing that Allah has bestowed upon you by maintaining your memory and keeping it free from troubles and ailments, and protecting your mind from mental illness and harm. How confused have the scientists been, and how much have they argued and differed concerning the interpretation of this phenomenon, yet despite that they have not reached any definitive conclusion about it!

This is indicative of man’s great ignorance of many things, and his inability to explain many of the secrets of the brain and other faculties. For more information, please see the following books:

And Allah knows best.

Whatever written of Truth and benefit is only due to Allah's Assistance and Guidance, and whatever of error is of me. Allah Alone Knows Best and He is the Only Source of Strength.
