Imam further explains that when the soul of such a man is drawn from him there will be much pressure on him, so perhaps he will return and be aware.
Imam sheds the light on the matter in his famous book of "the combat with the self" as following:
Again, if he is not affected, then in the grave, in the world of barzakh, and in the terrible perilous events which take place after death, he will suffer pressures and chastisement until he becomes purified and refined, and he will not go to hell.
God the Blessed and Supreme gave them intellect, He gave them the power to refine and purify themselves, He sent the prophets and awliya [the friends of God, saints, holy men] to guide people and to help them to reform themselves so that they do not fall into the severe chastisement of hell.
If these preventatives do not cause the awareness and refinement of man, God, the Merciful, will make him aware through other means: by various difficulties, afflictions, poverty, and illness.
Like an expert physician or a skilled and kind nurse, He tries to cure a sick man from dangerous spiritual illnesses.
If a servant is blessed by God, he will be faced with afflictions until he turns his attention to God the Almighty, and is refined.
This is the way, and other than this there is no way, but man must tread this path with his own feet until he reaches its conclusion.
If he does not reach any conclusion in this way, and the misled man is not cured, and he does not deserve the blessings of heaven, when his soul is drawn from him there will be much pressure on him, so perhaps he will return and be aware, Imam pointed out.
Again, if he is not affected, then in the grave, in the world of barzakh, and in the terrible perilous events which take place after death, he will suffer pressures and chastisement until he becomes purified and refined, and he will not go to hell.
