Give glad tidings to your Shi'ahs that their death will be eased, and they will be saved from the terror of the grave and Qayamat".
Narrowness of and Squeeze in the Grave (Fishare Qabr).
This event is so horrifying, that it makes a person shiver with fright in this very world. Amirul Mo'meneen Ali (A.S.) says: "O the servants of Allah! The state in the grave
of a person whose sins are not forgiven is more horrifying than death itself. Fear it's (grave's) narrowness, it's squeezing, it's imprisonment, and it's loneliness. Verily the
grave calls out daily: I am the house of loneliness, of terror and worms. Grave is like a garden of Paradise for a good doer, while it is like a dungeon of hell for the evil doer. Allah tells His enemies that He will send ninety nine serpents in their graves, who will tear their flesh and smash their bones, and this punishment will continue till the outbreak of Qayamat. if one of the serpents exhales toward this earth, all plants and trees will be destroyed. O servants of Allah! Your souls are tender, and your bodies delicate, you cannot confront any ordinary serpent of this world, how then will you face them". It is related that Imam Ja'far-as-Sadiq (A.S.) used to get up daily in the middle of the night and call out in a loud voice so that everyone in the house could hear, and would say:
اللهم اعني على هول المطلع ووسع على ضيق المضجع وارزقني
