"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." (Using translation from Nasāʾī 1308)
سَأَلْتُ رَسُولَ اللهِ ﷺ عَنْ عَذَابِ الْقَبْرِ فَقَالَ «نَعَمْ عَذَابُ الْقَبْرِ حَقٌّ» قَالَتْ عَائِشَةُ فَمَا رَأَيْتُ رَسُولَ اللهِ ﷺ يُصَلِّي صَلَاةً بَعْدُ إِلَّا تَعَوَّذَ مِنْ عَذَابِ الْقَبْرِ
