Religious ecstasy

Religious ecstasy - Psychology Wiki

Are you aware of any similar concept in Islam ?

in other words ,

does islam promise us with "ecstasy " ?!

Did you have any similar experience while practicing a religious ritual (praying , reciting the quran..etc.) ?

This might be what you're looking for.

Wujud - Wikipedia, the free encyclopedia

Or perhaps this.

Hope it helps.

Thanks for the link Student of X

I know those concepts exist in sufism..but i was looking for something with an evidence from the quran and sunna
i don't buy anything from sufism without an evidence...as it's a mixture of islamic and other non islamic mystical traditions

I was looking for what is purely islamic

for example :

From your link : The Sufis believe that anyone who experiences wajd brings back some residual knowledge from the object of his finding (wujud).

Aside from the fact that the sentence is "meaningless"...it also lack any islamic evidence i guess (a Quranic verse , a hadith , a narration...)
