Musnad Ahmad 2651

It was narrated that Abu Nadrah said: Ibn 'Abbas (رضي الله عنه) was on the minbar of Basrah and I heard him say: The Prophet of Allah (ﷺ) used to seek refuge with Allah, after every prayer, from four things. He would say: "I seek refuge with Allah from the torment of the grave, I seek refuge with Allah from the torment of Hell, I seek refuge with Allah from trials and tribulations (fitan) both visible and invisible, and I seek refuge with Allah from the tribulation of the one-eyed liar [the Dajjal]."
