"I asked the Messenger of Allah ﷺ about the torment of the grave, and he siad: 'Yes, the torment of the grave is real.'" 'Aishah said: "After that I never saw the Messenger of Allah ﷺ offer any prayer but he would seek refuge with Allah (SWT) from the torment of the grave."  

سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنْ عَذَابِ الْقَبْرِ فَقَالَ نَعَمْ عَذَابُ الْقَبْرِ حَقٌّ قَالَتْ عَائِشَةُ فَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُصَلِّي صَلاَةً بَعْدُ إِلاَّ تَعَوَّذَ مِنْ عَذَابِ الْقَبْرِ  

Aishah told him that the Messenger of Allah ﷺ used to say the following supplication in his prayer: Allahumma inni audhu bika min 'adhab ilqabri wa 'audhu bika min fitnatil-masihid-dajjal, wa 'audhu bika min fitnatil-mahya walmamati, Allahumma inni 'audhu bika min al-ma'thami wal-maghram ( O Allah, I seek refuge with You from the torment of the grave, and I seek refuge in You from the tribulation of the Al-Masihid-Dajjal, and I seek refuge with You from the trials of life and death. O Allah, I seek refuge in You from sin and debt.) Someone said to him: "How often you seek refuge from debt!" He said: "If a man gets into debt, when he speaks lies, and when he makes a promise, he betrays it."  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَدْعُو فِي الصَّلاَةِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْمَأْثَمِ وَالْمَغْرَمِ فَقَالَ لَهُ قَائِلٌ مَا أَكْثَرَ مَا تَسْتَعِيذُ مِنَ الْمَغْرَمِ فَقَالَ إِنَّ الرَّجُلَ إِذَا غَرِمَ حَدَّثَ فَكَذَبَ وَوَعَدَ فَأَخْلَفَ  

"I heard Abu Hurairah say: 'The Messenger of Allah ﷺ said: When one of you recites the tashahhud, let him seek refuge with Allah (SWT) from our things: From the torment of hell, from the torment of the grave, from the trials of life and death and from the evils of the Dajjal. Then let him pray for himself asking whatever he wants.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا تَشَهَّدَ أَحَدُكُمْ فَلْيَتَعَوَّذْ بِاللَّهِ مِنْ أَرْبَعٍ مِنْ عَذَابِ جَهَنَّمَ وَعَذَابِ الْقَبْرِ وَفِتْنَةِ الْمَحْيَا وَالْمَمَاتِ وَمِنْ شَرِّ الْمَسِيحِ الدَّجَّالِ ثُمَّ يَدْعُو لِنَفْسِهِ بِمَا بَدَا لَهُ
