The Messenger of Allah (way peace be upon him) said: When any one of you utters tashahhud (in prayer) he must seek refuge with Allah from four (trials) and should thus say:" O Allah! I seek refuge with Thee from the torment of the Hell, from the torment of the grave, from the trial of life and death and from the evil of the trial of Masih al-Dajjal" (Antichrist).
قَالَ رَسُولُ اللَّهِ ﷺ إِذَا تَشَهَّدَ أَحَدُكُمْ فَلْيَسْتَعِذْ بِاللَّهِ مِنْ أَرْبَعٍ يَقُولُ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ جَهَنَّمَ وَمِنْ عَذَابِ الْقَبْرِ وَمِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ وَمِنْ شَرِّ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ
