Abu Baseer says that I told Imam Ja’far-as-Sadiq (a.s.), “O son of the Prophet! Please admonish me from the wrath of Allah, for my heart has turned hard.” Imam (a.s.) replied,“O Abu Muhammad! Get ready for the lengthy life, the life of the hereafter, which is eternal. So worry about it and get ready for it. One day Jibra’eel came to the presence of the Holy Prophet Muhammad (s.a.w.s.) in a sad and serious mood. While other times whenever he came to the Prophet he came with a smiling face.
The Holy Prophet (s.a.w.s.) looked at him and said, “O Jibra’eel! What has happened to you, for you look sad and angry.” To which Jibra’eel replied, “The blower which was used to incite the flames of the fire of hell has been stopped.” The Prophet asked him as to what the blower was? Jibra’eel replied, “O Prophet! According to the orders of Allah, the fire of hell was given air with this blower for a thousand years till it turned white. Then again it was given air for a thousand years till it turned red. While again it was given air for a thousand years and ultimately it turned dark and black. If one drop of the Zaree’ (liquid which is the admixture of the sweat of the people of hell, and the wastage which will be oozing from the private parts of the fornicator women, which will be boiled in large vessels by the heat of the fire of hell, and the evil doers will be given to drink it) be poured in the seas in this world, the entire world would be ruined because of its filthiness. If one ring of the seventy feet chain to be bound in the necks of the people of hell be placed on the earth, it would melt because of intense heat. And if one shirt of the shirts of the people of hell be hung between the sky and the earth, the entire world would perish because of the bad odour emitting from it.” After saying this Jibra’eel and the Holy Prophet (s.a.w.s.) both wept.
When Allah saw this, He sent one of His Angels to Him. The Angel said, “O Prophet! Allah sends salutations to you, and says that surely He has kept this punishment far away from you.” After this whenever Jibra’eel came to the Prophet, He was in a good mood.”
Imam Sadiq (a.s.) continued, “On that day the dwellers of hell will become aware of Allah’s great chastisement, likewise the dwellers of Paradise will also become aware of Allah’s Mercy and Blessings. When the evildoers will be thrown into the fire of hell, they will try hard for seventy years and finally come to the mouth of hell. Then the Angels standing there will strike their heads with iron clubs, and they will again fall into the bottom of the pit. They will then be given new skins so as to repeat and prolong this punishment.”
Then Imam (a.s.) asked Abu Baseer,
“Is this enough for you”? He replied, “Verily it is enough.” Reference:Manazelul Akherah Shk Abbas Qummi (ra)
