The Prophet ﷺ said, "When a faithful believer is made to sit in his grave, then (the angels) come to him and he testifies that none has the right to be worshipped but Allah and Muhammad is Allah's Apostle. And that corresponds to Allah's statement: Allah will keep firm those who believe with the word that stands firm . . . (14.27). Narrated Shu'ba: Same as above and added, "Allah will keep firm those who believe . . . (14.27) was revealed concerning the punishment of the grave."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أُقْعِدَ الْمُؤْمِنُ فِي قَبْرِهِ أُتِيَ ثُمَّ شَهِدَ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ فَذَلِكَ قَوْلُهُ {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ} حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا غُنْدَرٌ حَدَّثَنَا شُعْبَةُ بِهَذَا وَزَادَ {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا} نَزَلَتْ فِي عَذَابِ الْقَبْرِ  

Messenger of Allah ﷺ said, "When a Muslim is questioned in his grave, he will testify that none has the right to be worshipped but Allah and that Muhammad is Messenger of Allah ﷺ, and that is what is meant by Allah's Statement:-- "Allah will keep firm those who believe with a Word that stands firm in this world and in the Hereafter." (14.27)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الْمُسْلِمُ إِذَا سُئِلَ فِي الْقَبْرِ يَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ فَذَلِكَ قَوْلُهُ {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الآخِرَةِ}  

When a Muslim is questioned in the grave he testifies that there is no god but Allah and that Muhammad is Allah’s Apostle. That is verified by Allah’s words: “Allah establishes those who believe with the word that stands firm.”  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ الْمُسْلِمَ إِذَا سُئِلَ فِي الْقَبْرِ فَشَهِدَ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ﷺ فَذَلِكَ قَوْلُ اللَّهِ ﷻ { يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ }  

[Machine] The Prophet ﷺ said, "When a believer testifies that there is no deity except Allah and acknowledges Muhammad as the Messenger of Allah ﷺ in his grave, then this is the saying of Allah, the Exalted, 'Allah keeps firm those who believe, with the firm word, in worldly life and in the Hereafter.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ «الْمُؤْمِنُ إِذَا شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَعَرَفَ مُحَمَّدًا رَسُولَ اللَّهِ ﷺ فِي قَبْرِهِ فَذَلِكَ قَوْلُ اللَّهِ جَلَّ وَعَلَا {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} »  

[Machine] The Prophet ﷺ said, "When a believer testifies that there is no god but Allah and recognizes Muhammad ﷺ in his grave, then that is Allah's statement: 'Allah will establish those who believe with the firm statement in the worldly life and in the Hereafter.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ «الْمُؤْمِنُ إِذَا شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَعَرَفَ مُحَمَّدًا ﷺ فِي قَبْرِهِ فَذَلِكَ قَوْلُهُ {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} »  

When a Muslim is questioned in the grave he testifies that there is no god but Allah and that Muhammad is Allah’s Apostle. That is verified by Allah’s words: “Allah establishes those who believe with the word that stands firm.” (Using translation from Abū Dāʾūd 4750)   

("إِنَّ الْمُؤْمِنَ إِذا شهد أَن لَّا إِله إِلا اللهُ، وعَرَفَ مُحمَّدًا في قَبْرِه فَذَلِكَ قوله تَعَالى: {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ ... } الآية ".  

"المؤمِن إِذَا شَهِدَ أنْ لَا إِلَه إِلَّا اللهُ، وَعَرَف محمدًا في قَبْرهِ فَذلِكَ قولُ اللهِ ﷻ {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ}.  

"المسلم إِذا سُئِلَ في القبر يشهد أَن لا إِله إلا الله، وأَن محمدًا رسولُ الله، فذلك قوله تعالى: {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} ".
