وَعَنْ شَدَّادِ بْنِ أَوْسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: " سَيِّدُ الِاسْتِغْفَارِ أَنْ تَقُولَ: اللَّهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعَتُ أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ وَأَبُوءُ بِذَنْبِي فَاغْفِرْ لِي فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ ". قَالَ: «وَمَنْ قَالَهَا مِنَ النَّهَارِ مُوقِنًا بِهَا فَمَاتَ مِنْ يَوْمِهِ قَبْلَ أَنْ يُمْسِيَ فَهُوَ مِنْ أَهْلِ الْجَنَّةِ وَمَنْ قَالَهَا مِنَ اللَّيْلِ وَهُوَ مُوقِنٌ بِهَا فَمَاتَ قَبْلَ أَنْ يُصْبِحَ فَهُوَ مِنْ أَهْلِ الْجَنَّةِ» . رَوَاهُ البُخَارِيّ
Shaddad ibn Aws reported that the Messenger of God (peace be upon him) said: ‘The foremost formula of seeking forgiveness is to say: “O God, You are my Lord; there is no deity but You. You created me, and I am Your servant. I keep Your covenant and promise as best I can. I seek refuge in You from the evil I have done. I acknowledge Your favor upon me, and I acknowledge my sin, so forgive me, for no one forgives sins except You.” Whoever says it during the day with certainty in it and dies that day before evening will be among the people of Paradise; and whoever says it at night with certainty in it and dies before morning will be among the people of Paradise.’ Al-Bukhari transmitted it. The Arabic source grades it sahih (al-Albani).
