And there are some supplications which are obligatory on certain [specific] occasions, like seeking refuge with Allaah from the four things [in the last tashhahud in the prayer]: from the punishment of Hell and the punishment of the grave, from the trials and tribulations of life and death and from the trial and temptation of Al-Maseeh Ad-Dajjaal, as occurs in the hadith of Bukhaari from Abu Hurairah (radiallaahu 'anhu) that he said:
The Prophet of Allaah (salallaahu 'alaihi wa sallam) said: When one of you finishes the final tashahhud, then let him seek refuge with Allaah from four...
So in this there is a clear order for the one who is praying to seek refuge from these four things at the end of his prayer.
Subhanak Allaahuma wa bihamdika ash-hadu anlaa illaaha illa anta astaghfiruka wa atubu ilayk
If I said anything correct, then it is from Allaah (subhanahu wa taa'ala), and if I erred, then that is from me and shaytan.
