"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.
Sahih Muslim Book 5, Hadith 170
