Muhammad bin Abi ‘Aishah said:“I heard Abu Hurairah say that the Messenger of Allah (ﷺ) said: ‘When anyone of you finishes the last Tashah-hud, let him seek refuge with Allah from four things: From the torment of Hell, from the torment of the grave, from the trials of life and death, and from the Fitnah (tribulation) of Masihud-Dajjal.’
