The Prophet Muhammad (saws) used to utter a dua during tashahud seeking refuge in Allah from the punishment from Hell and the torment of the grave, and from the trials of life and death, and from the trials and afflictions of Mesih ad dajjal. ‘Allaahumma inni ‘aoodhu bika min ‘adhaab Jahannam wa min ‘adhaab al-qabri wa min fitnat il-mahyaa wa’l-mamaat wa min sharri fitnat il-maseekh id-dajjaal (O Allaah, I seek refuge with You from the punishment of Hell and the punishment of the grave, and from the trials of life and death and from the worst of the turmoil of the Dajjaal (antichrist)).
