Prophet (saas) would supplicate with these words: "Allahumma inni a'udhu bika min fitnatin-nari wa 'adhabin-nar, wa min fitnatil-qabri wa 'adhabil-qabr, wa min sharri fitnatil-ghina wa min sharri fitnatil-faqr, wa min sharri fitnatil-masihid-dajjal. Allahumma aghsil khatayaya bima'ith-thalfi wal-barad, wa naqqi qalbi minal-khataya kama naqqaytath-thawbal-abyad minad-danas. Wa ba'id bayni wa bayna khatayaya kama ba'adta baynal-mashriqi wal-maghrib. Allahumma inni a'udhu bika minal-kasali wal-harami wal-ma'thami wal-maghrami (O Allah, I seek refuge with You from the tribulation of the Fire and the torment of the Fire, and from the tribulation of the grave, and from the evil of the tribulation of richness and the evil of the tribulation of poverty, and from the evil of the trial of the False Christ. O Allah! Wash away my sins with the water of snow and hail, and cleanse my heart from sin as a white garment is cleansed from filth, and put a great distance between me and my sins, as great as the distance You have made between the east and the west. O Allah! I seek refuge with You from laziness and old age, and from sins and debt)." (Using translation from Ibn Mājah 3838)
أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ النَّارِ وَفِتْنَةِ النَّارِ وَفِتْنَةِ الْقَبْرِ وَعَذَابِ الْقَبْرِ وَشَرِّ فِتْنَةِ الْغِنَى وَشَرِّ فِتْنَةِ الْفَقْرِ وَشَرِّ فِتْنَةِ الْمَسِيحِ الدَّجَّالِ اللهُمَّ اغْسِلْ خَطَايَايَ بِمَاءِ الثَّلْجِ وَالْبَرَدِ وَنَقِّ قَلْبِي مِنَ الْخَطَايَا كَمَا يُنَقَّى الثَّوْبُ الْأَبْيَضُ مِنَ الدَّنَسِ وَبَاعِدْ بَيْنِي وَبَيْنَ خَطَايَايَ كَمَا بَاعَدْتَبَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ اللهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْكَسَلِ وَالْهَرَمِ وَالْمَغْرَمِ وَالْمَأْثَمِ
