The Prophet ﷺ used to invoke Allah, saying, "Allahumma ighfirli khati'ati wa jahli wa israfi fi ʿAmri, wa ma anta a-'lamu bihi minni. Allahumma ighfirli hazali wa jiddi wa khata'i wa amdi, wa kullu dhalika 'indi."

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَدْعُو اللَّهُمَّ اغْفِرْ لِي خَطِيئَتِي وَجَهْلِي وَإِسْرَافِي فِي أَمْرِي وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي اللَّهُمَّ اغْفِرْ لِي هَزْلِي وَجِدِّي وَخَطَاىَ وَعَمْدِي وَكُلُّ ذَلِكَ عِنْدِي

" O Allah, forgive me my faults, my ignorance, my immoderation in my concerns. And Thou art better aware (of my affairs) than myself. O Allah, grant me forgiveness (of the faults which I committed) seriously or otherwise (and which I committed inadvertently and de- liberately. All these (failings) are in me. O Allah, grant me forgiveness from the fault which I did in haste or deferred, which I committed in privacy or in public and Thou art better aware of (them) than myself. Thou art the First and the Last and over all things Thou art Omnipotent."

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَدْعُو بِهَذَا الدُّعَاءِ اللَّهُمَّ اغْفِرْ لِي خَطِيئَتِي وَجَهْلِي وَإِسْرَافِي فِي أَمْرِي وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي اللَّهُمَّ اغْفِرْ لِي جِدِّي وَهَزْلِي وَخَطَئِي وَعَمْدِي وَكُلُّ ذَلِكَ عِنْدِي اللَّهُمَّ اغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ وَأَنْتَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ
