The Prophet ﷺ said: If anyone says in the morning or in the evening: "O Allah! Thou art my Lord; there is no god but Thee, Thou hast created me, and I am Thy servant and hold to Thy covenant and promise as much as I can; I seek refuge in Thee from the evil of what I have done: I acknowledge Thy favour to me, and I acknowledge my sin; pardon me, for none but Thee pardons sins, and dies during the daytime or during the night." he will go to Paradise. (Using translation from Abū Dāʾūd 5070)  

قَالَ رَسُولُ اللهِ ﷺ مَنْ قَالَ حِينَ يُصْبِحُ وَحِينَ يُمْسِي فَمَاتَ مِنْ يَوْمِهِ أَوْ لَيْلَتِهِ دَخَلَ الْجَنَّةَ مَنْ قَالَ اللهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ أَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ أَبُوءُ بِنِعْمَتِكَ وَأَبُوءُ بِذَنْبِي فَاغْفِرْ لِي إِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ  

[Machine] On the authority of the Prophet ﷺ , he said: "The chief of supplications is to say: 'O Allah, You are my Lord, there is no god worthy of worship except You. You created me and I am Your servant, and I am faithful to my covenant and promise to You as much as I am able. I seek refuge in Your favor and acknowledge my sins to You. So forgive me, for there is no one who forgives sins except You.' If a person says this in the morning, truly believing in it, and then dies that day, they will be from the people of Paradise. And if they say it in the evening, truly believing in it, and then dies that night, they will be from the people of Paradise." Abu Abdur-Rahman Husayn said: "In our opinion, this hadith is more authentic than that of Walid ibn Tha'labah, and I am more knowledgeable about Abdullah ibn Buraidah, and his narration is more correct."  

عَنِ النَّبِيِّ ﷺ قَالَ سَيِّدُ الِاسْتِغْفَارِ أَنْ تَقُولَ اللهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ أَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَبُوءُ لَكَ بِالنِّعْمَةِ وَأَبُوءُ لَكَ بِذَنْبِي فَاغْفِرْ لِي إِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ فَإِنْ قَالَهَا حِينَ يُصْبِحُ مُوقِنًا بِهَا ثُمَّ مَاتَ كَانَ مِنْ أَهْلِ الْجَنَّةِ وَإِنْ قَالَهَا بَعْدَمَا يُمْسِي مُوقِنًا بِهَا ثُمَّ مَاتَ كَانَ مِنْ أَهْلِ الْجَنَّةِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ حُسَيْنٌ أَثْبَتُ عِنْدَنَا مِنَ الْوَلِيدِ بْنِ ثَعْلَبَةَ وَأَعْلَمُ بِعَبْدِ اللهِ بْنِ بُرَيْدَةَ وَحَدِيثُهُ أَوْلَى بِالصَّوَابِ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ قَالَ حِينَ يُصْبِحُ وَحِينَ يُمْسِي اللهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ أَبُوءُ لَكَ بِالنِّعْمَةِ عَلَيَّ وَأَبُوءُ لَكَ بِذَنْبِي فَاغْفِرْ لِي فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ فَإِنْ قَالَهَا مُصْبِحًا فَمَاتَ مِنْ يَوْمِهِ غُفِرَ لَهُ وَأُدْخِلَ الْجَنَّةَ وَإِنْ قَالَهَا مُمْسِيًا فَمَاتَ مِنْ لَيْلَتِهِ غُفِرَ لَهُ وَأُدْخِلَ الْجَنَّةَ
