Dua at the end of Salah (Allahumma Inni A Uzu Bika)

اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنْ عَذَابِ جَهَنَّمَ وَأَعُوْذُ بِكَ مِنْ عَذَابِ الْقَبْرِ وَأَعُوْذُ بِكَ مِنْ فِتْنَةِ الْمَسِيْحِ الدَّجَّالِ وَأَعُوْذُ بِكَ مِنْ فِتْنَةِ الْمَحْيَا وَالْمَمَاتِ. اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنَ الْمَأْثَمِ وَمِنَ الْمَغْرَمِ

Transliteration

Allaahumma inni a`udhu bika min `adhaabi jahannam, wa a`udhu bika min `adhaabil-qabr, wa a`udhu bika min fitnatil-masihid-dajjaal, wa a`udhu bika min fitnatil-mahyaa wal-mamaat, Allaahumma inni a`udhu bika minal-ma'thami wa minal-maghram

Meaning

O Allah, I seek refuge with Thee from the torment of Hell, and I seek refuge with Thee from the torment of the grave, and I seek refuge with Thee from the trial of the Masih al-Dajjal (Antichrist) and I seek refuge with Thee from the trial of life and death. O Allah! I seek refuge with Thee from sin and debt.
