Al-Bara said about Allah will keep firm those who believe, with the word that stands firm in this world and in the Hereafter "It was revealed concerning the torment of the grave. (Using translation from Nasāʾī 2056)   

{يُثَبِّتُ اللهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا} [إبراهيم 27] قَالَ «نَزَلَتْ فِي عَذَابِ الْقَبْرِ»  

“Allah will keep firm those who believe, with the word that stands firm.” [14:27] This has been revealed concerning the torment of the grave. It will be said to him: ‘Who is your Lord?’ He will say: ‘My Lord is Allah, and my Prophet is Muhammad.’ This is what Allah says: Allah will keep firm those who believe, with the word that stands firm in this world (i.e. they will keep on worshipping Allah Alone and none else), and in the Hereafter (i.e., at the time of questioning in the grave).’” [14:27] (Using translation from Ibn Mājah 4269)  

عَنِ النَّبِيِّ ﷺ قَالَ {يُثَبِّتُ اللهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا} [إبراهيم 27] قَالَ نَزَلَتْ فِي عَذَابِ الْقَبْرِ يُقَالُ لَهُ مَنْ رَبُّكَ؟ فَيَقُولُ رَبِّيَ اللهُ وَنَبِيِّي مُحَمَّدٌ فَذَلِكَ قَوْلُهُ {يُثَبِّتُ اللهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} [إبراهيم 27]  

"When died this man die?" They said: "he died during the Jahiliyyah." So he was delighted and said: "Were it not that you would not bury one another, I would have prayed to Allah to make you hear the torment of the grave." (Using translation from Nasāʾī 2058)  

أَنَّ النَّبِيَّ ﷺ سَمِعَ صَوْتًا مِنْ قَبْرٍ فَقَالَ «مَتَى مَاتَ هَذَا؟» قَالُوا مَاتَ فِي الْجَاهِلِيَّةِ فَسُرَّ بِذَلِكَ وَقَالَ «لَوْلَا أَنْ لَا تَدَافَنُوا لَدَعَوْتُ اللهَ أَنْ يُسْمِعَكُمْ عَذَابَ الْقَبْرِ»  

" Messenger of Allah ﷺ went out after the sun had set and he heard some sound and said: It is the Jews who are being tormented in their graves. (Using translation from Muslim 2869)  

خَرَجَ رَسُولُ اللهِ ﷺ بَعْدَمَا غَرَبَتِ الشَّمْسُ فَسَمِعَ صَوْتًا فَقَالَ يَهُودُ تُعَذَّبُ فِي قُبُورِهَا
