 all human beings go through four steps of age:

• The age in the womb is where the body acquires its soul. The fetus is imbued with a soul from God. The soul however, is completely innocent and totally lacking of any worldly knowledge, which is reflected by a baby's helplessness.
• The age in the mortal world is the stage of life from the moment of birth from the womb to the moment of death.

  by The Grace and Mercy of Allah and if they have attained little in life, and were unrighteous in their actions—or were despite all evidence shown to them, bent on denying the truth of life once it was presented to them based on their own circumstances they shall go to Hell.This stage of life commences officially after the embodiment of Death is brought up and is slain, thus Death dies literally again and again, and no one will ever experience or behold the concept of Death everafter. Based on the verdict received which is brought upon by each person's individual deeds, actions, and circumstances in life, the Day of Judgement on which everyone is judged with the utmost sense of justice, each human will spend this stage of life in heaven or hell (which will be a place for purification of the soul so that one realizes the wrongs committed in life). However, those in hell are eligible to go to the state of heaven after being purified by that state described as hell if they "had an atom's worth of faith in them" and the soul is repentful.
