It was narrated from 'Abdullah bin 'Abbas that:
The Messenger of Allah used to teach them this supplication as he taught them surahs of the Quran: Allahumma inna na'udhu bika min 'adhabil-qabri wa a'udhu bika min fitnatil-masihid-dajjal, wa a'udhu bika min fitnatil-mahya wal-mamat (O Allah, We seek refuge with You from the torment of Hell, and I seek refuge with You from the torment of the grave, and I seek refuge with You from the trail of Al-Masihid-Dajjal, and I seek refuge with You from the trails of life and death.)
