[Machine] The Messenger of Allah ﷺ used to pray voluntary prayers, and I heard him saying, "O Allah, I seek refuge in You from the Hellfire, woe to the people of the Hellfire."  

البيهقي:٣٦٩٠ – أَخْبَرَنَا أَبُو بَكْرٍ أَحْمَدُ بْنُ الْحَسَنِ الْقَاضِي وَأَبُو سَعِيدٍ مُحَمَّدُ بْنُ مُوسَى بْنِ الْفَضْلِ قَالَا ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ إِسْحَاقَ ثنا عُبَيْدُ اللهِ بْنُ مُوسَى عَنِ ابْنِ أَبِي لَيْلَى عَنْ ثَابِتٍ الْبُنَانِيِّ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى عَنْ أَبِيهِ قَالَ

كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي تَطَوُّعًا فَسَمِعْتُهُ يَقُولُ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ النَّارِ وَيْلٌ لِأَهْلِ النَّارِ
