Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “When the deceased is buried in his grave, two black and blue angels come to him. One of them is called Munkar and the other is called Nakir. They will both say: What do you say about this man? He will say what he said before: He is the servant of Allah and His messenger, I bear witness there is no God but Allah and Muhammad is His servant and His messenger. They will both say: We knew you would say this! Then his grave is expanded by seventy cubits on each side, it is illuminated for him, and it is said to him: Sleep! He will say: May I return to my family to tell them? They will both say: Sleep like a bridegroom, whom none awakens but the most beloved of his family, until Allah resurrects him from his place of rest. If he was a hypocrite, he will say to the angels: I heard people saying something, so I said the same as them, for I do not know! They will both say: We knew you would say that! It will be said to the earth to constrict him, so it will constrict him by squeezing his ribs together. He will continue being punished until Allah resurrects him from that place of his.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قُبِرَ الْمَيِّتُ أَتَاهُ مَلَكَانِ أَسْوَدَانِ أَزْرَقَانِ يُقَالُ لِأَحَدِهِمَا الْمُنْكَرُ وَالْآخَرُ النَّكِيرُ فَيَقُولَانِ مَا كُنْتَ تَقُولُ فِي هَذَا الرَّجُلِ فَيَقُولُ مَا كَانَ يَقُولُ هُوَ عَبْدُ اللَّهِ وَرَسُولُهُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ فَيَقُولَانِ قَدْ كُنَّا نَعْلَمُ أَنَّكَ تَقُولُ هَذَا ثُمَّ يُفْسَحُ لَهُ فِي قَبْرِهِ سَبْعُونَ ذِرَاعًا فِي سَبْعِينَ ثُمَّ يُنَوَّرُ لَهُ فِيهِ ثُمَّ يُقَالُ لَهُ نَمْ فَيَقُولُ أَرْجِعُ إِلَى أَهْلِي فَأُخْبِرُهُمْ فَيَقُولَانِ نَمْ كَنَوْمَةِ الْعَرُوسِ الَّذِي لَا يُوقِظُهُ إِلَّا أَحَبُّ أَهْلِهِ إِلَيْهِ حَتَّى يَبْعَثَهُ اللَّهُ مِنْ مَضْجَعِهِ ذَلِكَ وَإِنْ كَانَ مُنَافِقًا قَالَ سَمِعْتُ النَّاسَ يَقُولُونَ فَقُلْتُ مِثْلَهُ لَا أَدْرِي فَيَقُولَانِ قَدْ كُنَّا نَعْلَمُ أَنَّكَ تَقُولُ ذَلِكَ فَيُقَالُ لِلْأَرْضِ الْتَئِمِي عَلَيْهِ فَتَلْتَئِمُ عَلَيْهِ فَتَخْتَلِفُ فِيهَا أَضْلَاعُهُ فَلَا يَزَالُ فِيهَا مُعَذَّبًا حَتَّى يَبْعَثَهُ اللَّهُ مِنْ مَضْجَعِهِ ذَلِكَ
