Imam in this regard has undertaken very serious and useful discussions through his theological works.
The late founder of the Islamic Republic in his famous book "the combat with the self" explains as following:
Enmity and contention exist in hell. The people of hell have conflicts, fighting and clawing at one another. If you quarrel for the sake of this world, beware that you are preparing hell for yourself, and you are on the way there.
There is no fighting for things of the other world. The people of the other world are pure and at peace with one another. Their hearts are overflowing with the love of God and servitude to Him. The love for the servants of God is the shadow of that very love for God. Do not set your hands on fire. Do not set ablaze the flames of hell. Hell is lit with the ugly works and deeds of man. These are the deeds of refractory man which set this fire.
It is narrated: “I passed hell when it was extinguished.” If a man does not light the fire by his works and deeds, hell will be extinguished.
The interior of this disposition is hell. To approach this disposition is to approach hell. When man passes away from this world and the curtains are drawn aside, he will realize,
“This is for what your own hands have sent before” (Q 3:182), and “and what they had done they shall find present” (Q18:49).
All of the works and deeds and words of man will be reflected in the other world. It is as if everything in our lives was being filmed, and in that world film will be shown, and one will be able to deny none of it. All of our actions and movements will be shown to us, in addition to the testimony given by our limbs and organs, Imam furthre explained.
“They shall say: ‘Allah who makes everything speak, has made us speak’” (Q 41:21).
Before God, who will make all things able to speak and bear witness, you will not be able to deny your ugly deeds or hide them. Think a little, look ahead, weigh the consequences of your deeds, keep in mind the perilous events which take place after death, the pressure of the grave, the world of barzakh (the period between death and resurrection), and do not neglect the difficulties which will follow that.
At least believe in hell. If a man believes in the perilous events which take place after death, he will change his way of life. If you had faith and certainty in these things, you would not live so freely and licentiously. You will try to guard you pen, your steps, and your tongue, in order to reform and purify yourselves.
