عَنْ أَنَسٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلّى الله عليه وسلّم قَالَ: الْعَبْدُ إِذَا وُضِعَ فِي قَبْرِهِ، وَتُوُلِّيَ وَذَهَبَ أَصْحَابُهُ حَتَّى إِنَّهُ لَيَسْمَعُ قَرْعَ نِعَالِهِمْ، أَتَاهُ مَلَكَانِ فَأَقْعَدَاهُ فَيَقُولاَنِ لَهُ مَا كُنْتَ تَقُولُ فِي هَذَا الرَّجُلِ مُحَمَّدٍ صلّى الله عليه وسلّم فَيَقُولُ أَشْهَدُ أَنَّهُ عَبْدُ الله وَرَسُولُهُ. فَيُقَالُ انْظُرْ إِلَى مَقْعَدِكَ مِنَ النَّارِ، أَبْدَلَكَ الله بِهِ مَقْعَدًا مِنَ الْجَنَّةِ ـ قَالَ النَّبِيُّ صلّى الله عليه وسلّم فَيَرَاهُمَا جَمِيعًا ـ وَأَمَّا الْكَافِرُ ـ أَوِ الْمُنَافِقُ ـ فَيَقُولُ لاَ أَدْرِي، كُنْتُ أَقُولُ مَا يَقُولُ النَّاسُ. فَيُقَالُ لاَ دَرَيْتَ وَلاَ تَلَيْتَ. ثُمَّ يُضْرَبُ بِمِطْرَقَةٍ مِنْ حَدِيدٍ ضَرْبَةً بَيْنَ أُذُنَيْهِ، فَيَصِيحُ صَيْحَةً يَسْمَعُهَا مَنْ يَلِيهِ إِلاَّ الثَّقَلَيْنِ.
It is narrated by Hazrat Anasra that the Prophetsa said: “When a person is laid in his grave and his companions have departed, to the point that he can hear the sound of their footsteps, two angels will come to him and make him sit up. They will ask, ‘What did you say about this man, Muhammadsa?’ He will reply, ‘I testify that he is Allah’s servant and His Messenger.’ Then, it will be said, ‘Look at your seat in Hell. Allah has replaced it for you with a seat in Paradise.’ The Prophetsa added, ‘The deceased will see both places. But as for the non-believer or the hypocrite, he will say [to the angels], “I do not know, I used to echo whatever the people said!” It will then be said, ‘You did not know, nor did you seek guidance.’ Subsequently, he will be struck with an iron hammer between his ears, and his scream will be heard by all those nearby, except humans and the jinn.”
