It was narrated from Ibn ‘Abbas (رضي الله عنه) that:

The Messenger of Allah (ﷺ) used to teach them this supplication as he would teach them a soorah from the Qur’an. He would say: “Say: O Allah, I seek refuge with You from the punishment of Hell; I seek refuge with You from the punishment of the grave; I seek refuge with You from the trial of the Dajjal; and I seek refuge with You from the trials of life and death.”
