From the books of the Sunnah
Duas from the books of the Sunnah that are not in the chapters of Hisn al-Muslim. Each shows its source and grade, and weak narrations are clearly marked.
أَسْتَغْفِرُ اللَّهَ الْعَظِيمَ الَّذِي لاَ إِلَهَ إِلاَّ هُوَ الْحَيُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ
Astaghfirul-lahal-ʿatheemal-lathee la ilaha illa huwal-hayyul-qayyoomu wa-atoobu ilayh.
I seek Allah's forgiveness, besides whom, none has the right to be worshipped except He, The Ever Living, The Self-Subsisting and Supporter of all, and I turn to Him in repentance.
Its virtue
Whoever says it will be forgiven, even if he had fled from the battlefield.
Say it once
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْهَمِّ وَالْحَزَنِ، وَأَعُوذُ بِكَ مِنَ الْعَجْزِ وَالْكَسَلِ، وَأَعُوذُ بِكَ مِنَ الْجُبْنِ وَالْبُخْلِ، وَأَعُوذُ بِكَ مِنْ غَلَبَةِ الدَّيْنِ وَقَهْرِ الرِّجَالِ
Allahumma innee aʿoothu bika minal-hammi walhazan, wa-aʿoothu bika minal-ʿajzi walkasal, wa-aʿoothu bika minal-jubni walbukhl, wa-aʿoothu bika min ghalabatid-dayni waqahrir-rijal.
O Allah, I seek refuge in Thee from care and grief, I seek refuge in Thee from incapacity and slackness, I seek refuge in Thee from cowardice and niggardliness, and I seek [refuge] in Thee from being overcome by debt and being put in subjection by men.
Say it once
يَا رَبِّ لَكَ الْحَمْدُ كَمَا يَنْبَغِي لِجَلاَلِ وَجْهِكَ وَلِعَظِيمِ سُلْطَانِكَ
Ya Rabbi, lakal-hamdu kama yanbaghi li-jalali wajhika wa li-ʿatheemi sultanik.
O Lord, to You is praise as befits the Glory of Your Face and the greatness of Your Might.
