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)."
