I did not hear this hadith from Allah's Apostle ﷺ directly but it was Zaid b. Thabit who narrated it from him. As Allah's Apostle ﷺ was going along with us towards the dwellings of Bani an-Najjar, riding upon his pony, it shied and he was about to fall. He found four, five or six graves there. He said: Who amongst you knows about those lying in the graves? A person said: It is I. Thereupon he (the Holy Prophet) said: In what state did they die? He said: They died as polytheists. He said: These people are passing through the ordeal in the graves. If it were not the reason that you would stop burying (your dead) in the graves on listening to the torment in the grave which I am listening to, I would have certainly made you hear that. Then turning his face towards us, he said: Seek refuge with Allah from the torment of Hell. They said: We seek refuge with Allah from the torment of Hell. He said: Seek refuge with Allah from the torment of the grave. They said: We seek refuge with Allah from the torment of the grave. He said: Seek refuge with Allah from turmoil, its visible and invisible (aspects), and they said: We seek refuge with Allah from turmoil and its visible and invisible aspects and he said: Seek refuge with Allah from the turmoil of the Dajjal, and they said We seek refuge with Allah from the turmoil of the Dajjal.  

أَبُو سَعِيدٍ وَلَمْ أَشْهَدْهُ مِنَ النَّبِيِّ ﷺ وَلَكِنْ حَدَّثَنِيهِ زَيْدُ بْنُ ثَابِتٍ قَالَ بَيْنَمَا النَّبِيُّ ﷺ فِي حَائِطٍ لِبَنِي النَّجَّارِ عَلَى بَغْلَةٍ لَهُ وَنَحْنُ مَعَهُ إِذْ حَادَتْ بِهِ فَكَادَتْ تُلْقِيهِ وَإِذَا أَقْبُرٌ سِتَّةٌ أَوْ خَمْسَةٌ أَوْ أَرْبَعَةٌ قَالَ كَذَا كَانَ يَقُولُ الْجُرَيْرِيُّ فَقَالَ مَنْ يَعْرِفُ أَصْحَابَ هَذِهِ الأَقْبُرِ فَقَالَ رَجُلٌ أَنَا قَالَ فَمَتَى مَاتَ هَؤُلاَءِ قَالَ مَاتُوا فِي الإِشْرَاكِ فَقَالَ إِنَّ هَذِهِ الأُمَّةَ تُبْتَلَى فِي قُبُورِهَا فَلَوْلاَ أَنْ لاَ تَدَافَنُوا لَدَعَوْتُ اللَّهَ أَنْ يُسْمِعَكُمْ مِنْ عَذَابِ الْقَبْرِ الَّذِي أَسْمَعُ مِنْهُ ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ تَعَوَّذُوا بِاللَّهِ مِنْ عَذَابِ النَّارِ قَالُوا نَعُوذُ بِاللَّهِ مِنْ عَذَابِ النَّارِ فَقَالَ تَعَوَّذُوا بِاللَّهِ مِنْ عَذَابِ الْقَبْرِ قَالُوا نَعُوذُ بِاللَّهِ مِنْ عَذَابِ الْقَبْرِ قَالَ تَعَوَّذُوا بِاللَّهِ مِنَ الْفِتَنِ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ قَالُوا نَعُوذُ بِاللَّهِ مِنَ الْفِتَنِ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ قَالَ تَعَوَّذُوا بِاللَّهِ مِنْ فِتْنَةِ الدَّجَّالِ قَالُوا نَعُوذُ بِاللَّهِ مِنْ فِتْنَةِ الدَّجَّالِ  

[Machine] While we were at the wall of Bani Najjar with the Messenger of Allah ﷺ , he was riding a mule, and his mule stumbled. Suddenly, there were graves in the wall. The Messenger of Allah ﷺ said, "Who knows these graves?" A man said, "I do, O Messenger of Allah." The Messenger of Allah ﷺ asked, "Who are they?" The man replied, "They died in shirk (polytheism)." The Messenger of Allah ﷺ said, "If it were not for the fact that you would stop burying them, I would ask Allah to let you hear the punishment of the grave that I hear. Verily, this Ummah (nation) is tested in their graves." Then he turned his face towards us and said, "Seek refuge with Allah from the punishment of the Hellfire, the punishment of the grave, and seek refuge with Allah from the trials, whether they appear or remain hidden. Seek refuge with Allah from the deception of the Dajjal (the False Messiah)."  

بَيْنَمَا نَحْنُ فِي حَائِطٍ لِبَنِي النَّجَّارِ مَعَ رَسُولِ اللَّهِ ﷺ وَهُوَ عَلَى بَغْلَةٍ فَحَادَتْ بِهِ بَغْلَتُهُ فَإِذَا فِي الْحَائِطِ أَقْبُرٌ فَقَالَ رَسُولُ اللَّهِ ﷺ «مَنْ يَعْرِفُ هَؤُلَاءِ الْأَقْبُرَ؟ » فَقَالَ رَجُلٌ أَنَا يَا رَسُولَ اللَّهِ قَالَ «مَا هُمْ؟ » قَالَ مَاتُوا فِي الشِّرْكِ قَالَ «لَوْلَا أَنْ لَا تَدَافَنُوا لَدَعَوْتُ اللَّهَ أَنْ يُسْمِعَكُمْ عَذَابَ الْقَبْرِ الَّذِي أَسْمَعُ مِنْهُ إِنَّ هَذِهِ الْأُمَّةَ تُبْتَلَى فِي قُبُورِهَا» ثُمَّ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ «تَعَوَّذُوا بِاللَّهِ مِنْ عَذَابِ النَّارِ وَعَذَابِ الْقَبْرِ وَتَعَوَّذُوا بِاللَّهِ مِنَ الْفِتَنِ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ تَعَوَّذُوا بِاللَّهِ مِنْ فِتْنَةِ الدَّجَّالِ»  

[Machine] While the Messenger of Allah ﷺ was within the walls of Banu Najjar and he was riding on his mule, and we were with him, he said, "Seek refuge with Allah from the torment of the grave, seek refuge with Allah from the torment of the fire." We said, "We seek refuge with Allah from the torment of the grave, we seek refuge with Allah from the torment of the fire." He said, "Seek refuge with Allah from the trials, whether apparent or hidden." We said, "We seek refuge with Allah from the trials, whether apparent or hidden." He said, "Seek refuge with Allah from the trial of the Dajjal (Antichrist)." They said, "We seek refuge with Allah from the trial of the Dajjal."
