Imam Khomeini explains the matter in his famous work of "an exposition on Forty Hadith" as saying:
Since the struggle of the self concludes here and man succeeds in driving off the legions of satanic armies from the empire of his soul, this land becomes the abode of angels of God and a place of worship of truthful servants of God.
Thus, the task of pursuing the journey towards God becomes easier, and the road to humanism is illuminated.
The doors of blessings from heaven and their ascending steps are opened to him, and the doors of hell and the descending steps thereof are closed on him. God Almighty views him with mercy and benevolence and unites him with His faithful and His blessed servants.
The path to divine knowledge, which is the ultimate purpose of creation of mankind and jinn, is opened to him. God Almighty guards him through this hazardous path.
I wished to refer to the third stage of self (nafs), wherein another struggle against the deceptions and temptations of Satan takes place. But, on later thought, this description seems to be out of place here, so I left it undiscussed, Imam Khomeini further explained.
Is it possible for someone to consider it possible that hell exists and that one may remain forever in its fire while at the same time doing wrong?
Can it be said that one who considers God Almighty to be present and watching and Who sees himself to be in the presence of the Lord, and who considers it possible that there should be retribution for his words and deeds, a reckoning and chastisement, and that in this world every word he speaks, every step he takes, every deed he does, is recorded by angels of Allah called ‘Raqib and ‘Atid,’ and they carefully record all his words and deeds, and in such a state, could he fearless of his own doing?
It is painful [to realize] that they do not even consider these truths to be possible. From the manners of some and their way of living it is obvious that they do not even consider the existence of a supernatural world to be possible, since the mere consideration of this possibility keeps man from committing many wrongs.
