For example...
For example, in the Qur'an, the fire that is promised in the next life is referred to as nar ul jahannam (the fire of hell) or nar ul-kubra ( the great fire), implying that what you experience in this life is the small fire in the form of anger, disappointment, agitation and unfulfilled desires. Also the experience of the garden is potentially with man here and now. In the same way, the experience of the event, the day of reckoning, can be echoed and reflected within man here and now.
When a significant event occurs in someone's life it can cause him to begin to witness or to fully awaken. Such an event brings light into the passage of existence. Man is moving in a tunnel propelled by the powers of nature, guided or misguided by habits of the past, circumstances of the present and projections of the future. He is in a cocoon. If there is a sudden break in it and that crack begins to widen, then for the person who has experienced it there is a major event, there is a waqi'a.
But when the great event, the yawm ul-qiyama, occurs, nobody can deny it. Everyone is subject to its power. It lifts up and brings down, blowing up planets, stars or aspects of the cosmos and collapsing other parts. One creation ends and another begins. The cosmic entities are compelled to move in opposite directions. A major uplifting, down-thrusting situation will occur.
It is the time when the hearts that are already enlightened are lifted and stripped of their burdens, and the hearts that have been tarnished and burdened are brought down. The mu min (believer) is elevated and the kafir (denier) or munafiq (hypocrite) is degraded. The day of reckoning is the final sorting out, the yawm ul-fasl (the day of separation into groups).
There are no gray areas; your state will be joy or misery, according to what you have directed yourself toward and earned during the short preface of this life. Those who have been uplifting themselves along the path of truth will be fully uplifted in the next life, and those who have been degrading themselves will be completely degraded. The next consciousness is timeless, and will therefore have the stamp of permanency upon it.
That is why it is called the final abode, for in it there is no movement.
