Sunan an-Nasa'i, Book 50, Hadith 79 (In-Book) ⓘ
It was narrated from Abu Hurairah that: The Messenger of Allah [SAW] used to say: "Allahumma inni a'udhu bika min 'adhabil-qabri, wa a'udhu bika min 'adhabin-nari, wa a'udhu bika min fitnatil-mahya wal-mamat wa a'udhu bika min sharril-masihid-dajjali (O Allah, I seek refuge with You from the torment of the grave, and I seek refuge with You from the torment of the Fire, and I seek refuge with You from the trials of life and death, and I seek refuge with You from the evil of the Al-Masihid-Dajjal.)"
أَخْبَرَنَا يَحْيَى بْنُ دُرُسْتَ، قَالَ حَدَّثَنَا أَبُو إِسْمَاعِيلَ، قَالَ حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، أَنَّ أَبَا سَلَمَةَ، حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ كَانَ يَقُولُ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَأَعُوذُ بِكَ مِنْ عَذَابِ النَّارِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ وَأَعُوذُ بِكَ مِنْ شَرِّ الْمَسِيحِ الدَّجَّالِ " .
