اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ فِتْنَةِ الْقَبْرِ وَمِنْ عَذَابِ الْقَبْرِ
Allahumma inni a'udhu bika min fitnatil-qabri wa min 'adhabil-qabr
O Allah, I seek refuge in You from the trial of the grave and from the punishment of the grave.
The Prophet ﷺ used to seek refuge from this so frequently that the Companions asked: "Is the punishment of the grave real?" He said: "Yes, seek refuge from it." He walked past two graves and said: "They are being punished, and not for anything major — one used to carry tales, and the other was not careful about urine." Small, habitual sins can lead to grave punishment. This du'a is a daily shield against that.
