Dispelling this Misconception:


First:

The torment of the grave and enjoyments therein is not a myth invented by Muhammad (Allah’s pace and blessing be upon him), rather this issue was widespread before him (Allah’s pace and blessing be upon him) among the Jews as we have the evidence of the two Jewish old ladies who talked to Aisha (May Allah be pleased with her) about it… as it is confirmed in Al Bukhary Corrects chapter (Seeking Refuge with Allah from Torment of the Grave) number 5889:
Narrated `Aisha:
Two old ladies from among the Jewish ladies entered upon me and said' "The dead are punished in their graves," but I thought they were telling a lie and did not believe them in the beginning. When they went away and the Prophet entered upon me, I said, "O Allah's Apostle! Two old ladies.." and told him the whole story. He said, "They told the truth; the dead are really punished, to the extent that all the animals hear (the sound resulting from) their punishment." Since then I always saw him seeking refuge with Allah from the punishment of the grave in his prayers.
And in addition to this the Holy Quran has told about punishing Pharaoh and his people-they are of the old nations- they are exposed to Fire in the morning and in the evening before the Day of the Judgment and the day of Resurrection…
The Fire, they are exposed to it morning and evening. And the Day the Hour appears [it will be said], "Make the people of Pharaoh enter the severest punishment." (Ghafir 46)
