Abu Nadrah (may Allah have mercy on him) says that once Sayyiduna Ibn Abbas (may Allah be pleased with them both) was present on the pulpit of the central mosque of Basra. I heard him saying that the Prophet (peace and blessings be upon him) used to seek refuge from four things after prayer and used to say: «أَعُوذُ بِاللّٰهِ مِنْ عَذَابِ الْقَبْرِ وَأَعُوذُ بِاللّٰهِ مِنْ عَذَابِ النَّارِ وَأَعُوذُ بِاللّٰهِ مِنْ الْفِتَنِ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ وَأَعُوذُ بِاللّٰهِ مِنْ فِتْنَةِ الْأَعْوَرِ الْكَذَّابِ» "I seek refuge with Allah from the punishment of the grave, I seek refuge with Allah from the punishment of Hell, I seek refuge with Allah from the trials of life and death, and I seek refuge with Allah from the trial of the false messiah, the one-eyed Dajjal, who will be a great liar."
