Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "When anyone of you has done his Tashahhud during Salat (prayer), he should seek refuge in Allah against four things and say: "Allahumma inni a'udhu bika min 'adhabi jahannam, wa min 'adhabil-qabr, wa min fitnatil-mahya wal-mamat, wa min sharri fitnatil-masihid-dajjal (O Allah! I seek refuge in You from the torment of Hell, from the torment of the grave, from the trials of life and death, and from the mischief of Al-Masih Ad-Dajjal (Antichrist)."[Muslim].
