Anyway...
Anyway, if the fear of death is due to the place and path being unfamiliar, then it is necessary that the reality of death be completely comprehended and one's conviction strengthened.
In addition to this, it is necessary to obtain the necessary information by means of the Revelation and the traditions of the Infallible Imams (pbut) and the righteous people, regarding the stages, places of danger and the other particularities of death and after it, then believe in them and prepare oneself to encounter them.
Just like a person, who during the course of a journey, finds himself lonely and unaware of his whereabouts, manages to lessen his perplexity with the help of necessary information, maps and equipment's, we too must obtain the map of the way and the necessary information from authentic and reliable sources.
In a tradition from Imam Ali ibn Muhammed (pbuh), it is narrated that he (pbuh) approached one of his companions who was sick and in a state of crying and grieving and complaining due to fear of death.
The Imam (pbuh) then addressed him saying: "O servant of God, you fear death because you do not comprehend it." Then the Imam (pbuh) presented an example and said: "If you had become dirty, and due to the excess of dirt and dirtiness you were in suffering and inconvenience, and you knew that the cure for all this lay in your taking a shower, would you wish to go to a bath and clean yourself or would you wish to remain in the same state of dirtiness and as a result continue to undergo the suffering." The sick man said, "Yes, I would wish to take the shower." Then the Imam (pbuh) replied: "death (for you) is the very same shower." The point to be considered in the above tradition is that, the sick person was one of the companions of the Imam (pbuh) and was aware of the Islamic insight regarding death, but in spite of this, was intensely fearful of death.
And so, the Imam (pbuh) by presenting an example explained to him the states and circumstances after death and thus calmed him. 3. Lack of preparation Some of the people have comprehended the reality of death and are also aware of the Islamic insight regarding death. On the other hand, they have also obtained some information regarding the stations and the journey after death, however, in spite of all this, they still fear death.
