Abdullah bin `Abbas narrated:that the Messenger of Allah (ﷺ) used [to teach them this supplication as he used] to teach them a Surat of the Quran: “O Allah, indeed, I seek refuge in you from the punishment of Hell, and from the punishment of the grave, and I seek refuge in You from the trial of the false Masih, and I seek refuge in You from the trial of living and dying. (Allāhumma innī a`ūdhu bika min `adhābi jahannam, wa min `adhābil-qabr, wa a`ūdhu bika min fitnatil-masīḥid-dajjāl, wa a`ūdhu bika min fitnatil-maḥyā wal-mamāt)”
