Messenger of Allah ﷺ used to invoke (Allah): "Allahumma ini aʿudhu bika min 'adhabi-l-Qabr, wa min 'adhabi-nnar, wa min fitnati-l-mahya wa-lmamat, wa min fitnati-l-masih ad-dajjal. (O Allah! I seek refuge with you from the punishment in the grave and from the punishment in the Hell fire and from the afflictions of life and death, and the afflictions of Al-Masih Ad-Dajjal."
كَانَ رَسُولُ اللَّهِ ﷺ يَدْعُو اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَمِنْ عَذَابِ النَّارِ وَمِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ وَمِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ
