Sunan Abi Dawud, Hadith 979 ⓘ
Narrated Abdullah ibn Abbas: The Prophet used to say after the tashahhud: "O Allah, I seek refuge in Thee from the punishment in Hell, and I seek refuge in Thee from the punishment in the grave, and I seek refuge in Thee from the trial of antichrist, and I seek refuge in Thee from the trial of life and death."
حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، أَخْبَرَنَا عُمَرُ بْنُ يُونُسَ الْيَمَامِيُّ، حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ يَقُولُ بَعْدَ التَّشَهُّدِ " اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ جَهَنَّمَ وَأَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الدَّجَّالِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ " .
