mishkat_al_masabih:885وَعَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُعَلِّمُهُمْ هَذَا الدُّعَاءَ كَمَا يُعَلِّمُهُمُ السُّورَةَ مِنَ الْقُرْآنِ يَقُولُ: «قُولُوا اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ جَهَنَّمَ وَأَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ» . رَوَاهُ مُسْلِمٌ
Ibn ‘Abbas said that the Prophet used to teach them this prayer just as he used to teach them a sura of the Qur’an, telling them te say, “O God, I seek refuge in Thee from the punishment in jahannam, I seek refuge in Thee from the punishment in the grave, I seek refuge in Thee from the trial of the antichrist, and I seek refuge in Thee from the trial of life and death.” Muslim transmitted it.
النبي كان يعلمهم هذا الدعاء كما يعلمهم السورة من القرآن
