\nNarrated Abu Bakr As-Siddiq:\n \n\nI asked Allah's Messenger (ﷺ) to teach me an invocation so that I may invoke Allah with it in my prayer. He \ntold me to say, "Allahumma inni zalumtu nafsi zulman kathiran, Wala yaghfiru dh-dhunuba illa anta, \nfa ghfir li maghfiratan min `indika, wa r-hamni, innaka anta l-ghafuru r-rahim (O Allah! I have done \ngreat injustice to myself and none except You forgives sins, so bestow on me a forgiveness from You, \nand Have Mercy on me, You are the Forgiver, the Merciful).\n

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ أَبِي الْخَيْرِ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، عَنْ أَبِي بَكْرٍ الصِّدِّيقِ ـ رضى الله عنه ـ‏.‏ أَنَّهُ قَالَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم عَلِّمْنِي دُعَاءً أَدْعُو بِهِ فِي صَلاَتِي‏.‏ قَالَ ‏\n"‏ قُلِ اللَّهُمَّ إِنِّي ظَلَمْتُ نَفْسِي ظُلْمًا كَثِيرًا وَلاَ يَغْفِرُ الذُّنُوبَ إِلاَّ أَنْتَ، فَاغْفِرْ لِي مَغْفِرَةً مِنْ عِنْدِكَ، وَارْحَمْنِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ ‏"‏‏.‏
