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}  

This verse: "Allah grants steadfastness to those who believe with firm word," was revealed in connection with the torment of the grave. It would be said to him: Who is your Lord? And he would say: Allah is my Lord and Muhammad is my Apostle ﷺ, and that is (what is implied) by the words of Allah, the Exalted: "Allah keeps steadfast those who believe with firm word in this world and in the Hereafter."  

عَنِ النَّبِيِّ ﷺ قَالَ { يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ} قَالَ نَزَلَتْ فِي عَذَابِ الْقَبْرِ فَيُقَالُ لَهُ مَنْ رَبُّكَ فَيَقُولُ رَبِّيَ اللَّهُ وَنَبِيِّيَ مُحَمَّدٌ ﷺ فَذَلِكَ قَوْلُهُ ﷻ { 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 }  

that regarding Allah's saying: Allah will keep firm those who believe, with the word that stands firm in this world and in the Hereafter (14:27). The Prophet ﷺ said: "In the grave, when it is said to him: 'Who is your Lord? What is your religion? And who is your Prophet?'"  

عَنِ النَّبِيِّ ﷺ فِي قَوْلِ اللَّهِ ( يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الآخِرَةِ ) قَالَ فِي الْقَبْرِ إِذَا قِيلَ لَهُ مَنْ رَبُّكَ وَمَا دِينُكَ وَمَنْ نَبِيُّكَ؟  

[Machine] The Prophet ﷺ said about the grave: When he is asked, he will recognize his Lord, and he will say something that I do not remember. That is what Allah says: "Allah will keep firm those who believe, with the word that stands firm in this worldly life and in the Hereafter." [Ibrahim 27]  

أَنَّ النَّبِيَّ ﷺ قَالَ فِي الْقَبْرِ إِذَا سُئِلَ فَعَرَفَ رَبَّهُ قَالَ وَقَالَ شَيْئًا لَا أَحْفَظُهُ فَذَلِكَ قَوْلُهُ ﷻ {يُثَبِّتُ اللهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} [إبراهيم 27]  

[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 ".  

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)   

"إِذَا أُقعِدَ المؤمنُ في قَبْرِه إلى ثمَّ شَهَدَ أن لا إِلَهَ إِلا الله، وأنَّ محمدًا رسولُ الله، فذلك قَوْله: يثبِّتُ اللهُ الذين آمنوا بالقولِ الثابتِ".  

"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} ".
