Seek refuge with Allah from the torment of Hell, seek refuge with Allah from the torment of the grave, and seek refuge with Allah from the trial of Masih al-Dajjal and seek refuge with Allah from the trial of life and death.
The Apostle of Allah (ﷺ) used to supplicate in prayer thus:" O Allah! I seek refuge with Thee from the torment of the grave, and I seek refuge with Thee from the trial of the Masih al-Dajjal (Antichrist) and I seek refuge with Thee from the trial of life and death. O Allah! I seek refuge with Thee from sin and debt." She ('A'isha) reported: Someone said to him - (the Holy Prophet): Messenger of Allah! why is it that you so often seek refuge from debt? He said: When a (person) incurs debt, (he is obliged) to tell lies and break promise.
"Say, O Allah, we seek refuge with Thee from the torment of Hell. And I seek refuge with Thee from the torment of the grave, and I seek refuge with Thee from the trial of al-Masih ad-Dajjal, and I seek refuge with Thee from the trial of life and death." Muslim b. Hajjaj said: It has reached me that Tawus said to his son: Did you make this supplication in prayer? He said: No. (Upon this) he (Tawus) said: Repeat the prayer. Tawus has narrated this hadith through three or four (transmitters) with words to the same effect.
When the Messenger of Allah (ﷺ) finished his prayer. He begged forgiveness three times and said: O Allah! Thou art Peace, and peace comes from Thee; Blessed art Thou, O Possessor of Glory and Honour. Walid reported: I said to Auza'i: How is the seeking of forgiveness? He replied: You should say: I beg forgiveness from Allah, I beg forgiveness from Allah."
When the Messenger of Allah (ﷺ) pronounced salutation, he salutation longer than it took him to say: O Allah: Thou art Peace, and peace comes from Thee, blessed art Thou, Possessor of Glory and ]Honour; and in the narration of Ibn Numair the words are:" O Possessor of Glory and Honour."
