وَلَقَدْ أَهْلَكْنَا ٱلْقُرُونَ مِن قَبْلِكُمْ لَمَّا ظَلَمُوا۟ ۙ وَجَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ وَمَا كَانُوا۟ لِيُؤْمِنُوا۟ ۚ كَذَٰلِكَ نَجْزِى ٱلْقَوْمَ ٱلْمُجْرِمِينَ
We destroyed the generations before you when they did wrong; and their messengers (from Allah) came unto them with clear proofs (of His Sovereignty) but they would not believe. Thus do We reward the guilty folk.

Chapter: To seek refuge from punishment of the grave
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 (ﷺ) entered upon me, I said, "O Allah's Messenger (ﷺ)! 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.
