We relate in the Sahihs of al-Bukhari and Muslim, from A’ishah (May Allah be pleased with her), who reported that the Messenger of Allah (May Allah grant him peace and blessings) used to make dua in salah saying:
O Allah, I seek Your protection from the punishment in the grave, I seek Your protection from the trials of the anointed Dajjal, and I seek Your protection from the trials of death and life. O Allah, I seek Your protection from misdeeds and debt.
الَّلهُمَّ إنِّي أَعُوذُ بِكَ مِنْ عَذَابِ القَبْرِ، وَأَعُوذُ بِكَ مِن فِتنَةِ المَسِيحِ الدَّجَّالِ، وَأعُوذُ بِكَ مِن فِتنَةِ المَحْيَا وَالمَمَاتِ، الَّلهُمَّ إنِّي أَعُوذُ بِكَ مِنَ المَأْثَمِ وَالمَغْرَمِ
Allahumma inni a’udhu bika min ‘adhabi-l-qabr, wa a’udhu bika min fitnati-l-masihi-d-Dajjal, wa a’udhu bika min fitnati-l-mahya wa-l-mamat, Allahumma inni a’udhu bika min al-ma’thami wa-l-maghram.
