Narrated Anas bin Malik: Allah’s Messenger (ﷺ) said, “When (Allah’s) slave is put in his grave and his companions return and he even hears their footsteps, two angels come to him and make him sit and ask, ‘What did you use to say about this man (Muhammad)?’ The mu’min will say, ‘I testify that he is Allah’s slave and His Apostle.’ Then they will say to him, ‘Look at your place in the Hell Fire; Allah has given you a place in Paradise instead of it.’ So he will see both his places.” (Qatada said, “We were informed that his grave would be made spacious.” Then Qatada went back to the narration of Anas who said;)
Whereas a hypocrite or a disbeliever will be asked, “What did you use to say about this man.” He will reply, “I do not know; but I used to say what the people used to say.” So they will say to him, “Neither did you know nor did you take the guidance.” Then he will be hit with iron hammers once, that he will send such a cry as everything near him will hear, except Jinns and human beings.
حَدَّثَنَا عَيَّاشُ بْنُ الْوَلِيدِ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّهُ حَدَّثَهُمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ” إِنَّ الْعَبْدَ إِذَا وُضِعَ فِي قَبْرِهِ، وَتَوَلَّى عَنْهُ أَصْحَابُهُ، وَإِنَّهُ لَيَسْمَعُ قَرْعَ نِعَالِهِمْ، أَتَاهُ مَلَكَانِ فَيُقْعِدَانِهِ فَيَقُولاَنِ مَا كُنْتَ تَقُولُ فِي الرَّجُلِ لِمُحَمَّدٍ صلى الله عليه وسلم. فَأَمَّا الْمُؤْمِنُ فَيَقُولُ أَشْهَدُ أَنَّهُ عَبْدُ اللَّهِ وَرَسُولُهُ. فَيُقَالُ لَهُ انْظُرْ إِلَى مَقْعَدِكَ مِنَ النَّارِ، قَدْ أَبْدَلَكَ اللَّهُ بِهِ مَقْعَدًا مِنَ الْجَنَّةِ، فَيَرَاهُمَا جَمِيعًا ”. قَالَ قَتَادَةُ وَذُكِرَ لَنَا أَنَّهُ يُفْسَحُ فِي قَبْرِهِ. ثُمَّ رَجَعَ إِلَى حَدِيثِ أَنَسٍ قَالَ ” وَأَمَّا الْمُنَافِقُ وَالْكَافِرُ فَيُقَالُ لَهُ مَا كُنْتَ تَقُولُ فِي هَذَا الرَّجُلِ فَيَقُولُ لاَ أَدْرِي، كُنْتُ أَقُولُ مَا يَقُولُ النَّاسُ. فَيُقَالُ لاَ دَرَيْتَ وَلاَ تَلَيْتَ. وَيُضْرَبُ بِمَطَارِقَ مِنْ حَدِيدٍ ضَرْبَةً، فَيَصِيحُ صَيْحَةً يَسْمَعُهَا مَنْ يَلِيهِ، غَيْرَ الثَّقَلَيْنِ ”.
