What does “Life in Barzakh” mean? The short answer is…
Dictionary meaning of the word “barzakh” is an obstacle, curtain, and separative border between two things. Its meaning as a religious term is “the grave life which starts after death and will continue until resurrection on the Judgment Day.’’ This is what is meant with the word “barzakh” that takes place in the verse “And behind them is a barrier until the Day they are resurrected.” (Mu’minun, 23/100). According to this, every deceased person is going to enter the barzakh life.
