Hisnul Muslim 56

After the final tashahhud and before salam

اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ القَبْر، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ، وَأَعُوذُ بِكَ مِنْ فِتْنَةِ الْمَحْـيَا وَالْمَمَاتِ . اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْمَأْثَمِ وَالْمَغْرَمِ

Allaahumma 'innee 'a'oothu bika min 'athaabil-qabri, wa 'a'oothu bika min fitnatil-maseehid-dajjaali, wa 'a'oothu bika min fitnatil-mahyaa walmamaati. Allaahumma 'innee 'a'oothu bika minal-ma'thami walmaghrami.

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.
