After tashahhud #1
An-Nasa'i: 1310, Abu Dawud: 880
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ. اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ الْمَأْثَمِ وَالْمَغْرَمِ
O Allah, I seek refuge in You from the punishment of the grave, and I seek refuge in You from the trial of the False Messiah, and I seek refuge in You from the trials of life and death. O Allah, I seek refuge in You from sin and from debt.
