"The Messenger of Allah stood up and mentioned the trail with which a person will be tested in his grave. When he mentioned that the people became restless, which prevented me from understanding what the Messenger of Allah had said. When they settled down, I said to a man who was near me: 'May Allah bless you, what did the end?' he said: 'It has been revealed to me that you will be tested in your graves with a trial close to that of the Dajjal."' (Using translation from Nasāʾī 2062)  

أَنَّهُ سَمِعَ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ تَقُولُ قَامَ رَسُولُ اللهِ ﷺ «فَذَكَرَ الْفِتْنَةَ الَّتِي يُفْتَنُ بِهِ الْمَرْءُ فِي قَبْرِهِ» فَلَمَّا ذَكَرَ ذَلِكَ ضَجَّ الْمُسْلِمُونَ ضَجَّةً حَالَتْ بَيْنِي وَبَيْنَ أَنْ أَفْهَمَ كَلَامَ رَسُولِ اللهِ ﷺ فَلَمَّا سَكَنَتْ ضَجَّتُهُمْ قُلْتُ لِرَجُلٍ قَرِيبٍ مِنِّي أَيْ بَارَكَ اللهُ فِيكَ مَاذَا قَالَ رَسُولُ اللهِ ﷺ فِي آخِرِ قَوْلِهِ؟ قَالَ قَالَ «قَدْ أُوحِيَ إِلَيَّ أَنَّكُمْ تُفْتَنُونَ فِي الْقُبُورِ قَرِيبًا مِنْ فِتْنَةِ الدَّجَّالِ»
