أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ يَحْيَى، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَسْتَعِيذُ مِنْ عَذَابِ الْقَبْرِ وَمِنْ فِتْنَةِ الدَّجَّالِ وَقَالَ ‏
"‏ إِنَّكُمْ تُفْتَنُونَ فِي قُبُورِكُمْ ‏"‏ ‏.‏

It was narrated from Aishah that: the Prophet used to seek refuge with Allah from the torment of the grave and the trial of the Dajjal, and he said: "You will be tested in your graves."
