The Messenger of Allah ﷺ often would say, "subḥāna Allāhi wa-bi-ḥamdihī, astaghfiru Allāh wa-atūbu ilayhi (Glory be to Allah and with His praise, I seek the forgiveness of Allah and I repent to Him.)"

She said: I asked: Messenger of Allah, I see that you often repeat the saying subḥāna Allāhi wa-bi-ḥamdihī astaghfiru Allāh wa-atūbu ilayhi. He said, "My Lord informed me that I would soon see a sign in my Ummah. So when I see it I often say: subḥāna Allāhi wa-bi-ḥamdihī, astaghfiru Allāh wa-atūbu ilayhi. Indeed I saw it ˹when this āyah˺ was revealed: 'When the Help of Allah and the victory came,' i.e. Conquest of Makkah, 'And you see the people entering into the religion of Allah in multitudes, Then exalt ˹Him˺ with praise of your Lord and ask forgiveness of Him. Indeed, He is ever Accepting of repentance.' (Naṣr 110:1-3"  

كَانَ رَسُولُ اللَّهِ ﷺ يُكْثِرُ مِنْ قَوْلِ: «(سُبْحَانَ اللَّهِ وَبِحَمْدِهِ، أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ۔)»

قَالَتْ فَقُلْتُ: يَا رَسُولَ اللَّهِ أَرَاكَ تُكْثِرُ مِنْ قَوْلِ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ۔ فَقَالَ: «خَبَّرَنِي رَبِّي أَنِّي سَأَرَى عَلاَمَةً فِي أُمَّتِي، فَإِذَا رَأَيْتُهَا أَكْثَرْتُ مِنْ قَوْلِ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ، فَقَدْ رَأَيْتُهَا: {إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ} فَتْحُ مَكَّةَ {وَرَأَيْتَ النَّاسَ يَدْخُلُونَ فِي دِينِ اللَّهِ أَفْوَاجًا * فَسَبِّحْ بِحَمْدِ رَبِّكَ وَاسْتَغْفِرْهُ إِنَّهُ كَانَ تَوَّابًا}۔»  

[Machine] The Messenger of Allah ﷺ used to frequently say before his death, "SubhanAllah wa bihamdihi, astaghfirullah wa atubu ilayhi." I said, "O Messenger of Allah, you supplicate with a supplication that you did not use to supplicate with before today." He said, "Indeed, my Lord has informed me that I will see a sign in my Ummah, and when I see that sign, I should say 'SubhanAllah wa bihamdihi' and seek forgiveness from Him. Indeed, I have seen that sign when the victory of Allah and the conquest comes, and you see the people entering the religion of Allah in multitudes." [Surah An-Nasr: 2]  

كَانَ رَسُولُ اللهِ ﷺ يُكْثِرُ أَنْ يَقُولَ قَبْلَ مَوْتِهِ سُبْحَانَ اللهِ وَبِحَمْدِهِ أَسْتَغْفِرُ اللهَ وَأَتُوبُ إِلَيْهِ قَالَتْ وَكَانَ يُكْثِرُ أَنْ يَقُولَهُ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّكَ تَدْعُو بِدُعَاءٍ لَمْ تَكُنْ تَدْعُو بِهِ قَبْلَ الْيَوْمِ فَقَالَ إِنَّ رَبِّي ﷻ أَخْبَرَنِي أَنِّي سَأَرَى عَلَمًا فِي أُمَّتِي وَأَنِّي إِذَا رَأَيْتُ ذَلِكَ الْعَلَمَ أَنْ أُسَبِّحَ بِحَمْدِهِ وَأَسْتَغْفِرَهُ فَقَدْ رَأَيْتُ ذَلِكَ {إِذَا جَاءَ نَصْرُ اللهِ وَالْفَتْحُ وَرَأَيْتَ النَّاسَ يَدْخُلُونَ فِي دِينِ اللهِ أَفْوَاجًا} [النصر 2]  

[Machine] The Messenger of Allah ﷺ used to often say before his death, "SubhanAllah wa bihamdihi, astaghfirullah wa atubu ilayhi." So I said, "O Messenger of Allah, you utter a lot of supplications that you did not used to utter before this?" He replied, "Verily, my Lord, the Exalted and Glorious, has told me that He would send down (the news of) knowledge to me until I would see a sign which every Muslim would acknowledge. And the event which is to take place (in the near future) had already taken place, so there is no use in supplicating for it. So in this case, uttering (the supplication) is the cause of my happiness and expressing gratitude (to Allah), and I shall be the first amongst the people to present myself before Allah in absolute purity."  

كَانَ رَسُولُ اللَّهِ ﷺ يُكْثِرُ قَبْلَ مَوْتِهِ أَنْ يَقُولَ «سُبْحَانَ اللَّهِ وَبِحَمْدِهِ أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ» قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّكَ لِتُكْثِرَ مِنْ دُعَاءٍ لَمْ تَكُنْ تَدْعُو بِهِ قَبْلَ ذَلِكَ؟ قَالَ «إِنَّ رَبِّي جَلَّ وَعَلَا أَخْبَرَنِي أَنَّهُ سَيُرِينِي عِلْمًا فِي أُمَّتِي فَأَمَرَنِي إِذَا رَأَيْتُ ذَلِكَ الْعِلْمَ أَنْ أُسَبِّحَهُ وَأَحْمَدَهُ وَأَسْتَغْفِرَهُ وَإِنِّي قَدْ رَأَيْتُهُ {إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ} فَتْحُ مَكَّةَ»  

"خَبَّرنِى ربِّى أَنِّى سَأَرَى عَلَامَةً في أُمَّتِى فَإِذَا رَأيْتُهَا أَكْثَرتُ مِن قَوْل: سُبْحَانَ اللَّه وَبحَمْدِه، أَسْتَغْفِرُ اللَّه وَأَتُوبُ إِلَيْهِ، فَقَدْ رَأَيْتُهَا {إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ} (فتح) مكة: {وَرَأَيْتَ النَّاسَ يَدْخُلُونَ فِي دِينِ اللَّهِ أَفْوَاجًا (2) فَسَبِّحْ بِحَمْدِ رَبِّكَ وَاسْتَغْفِرْهُ إِنَّهُ كَانَ تَوَّابًا (3)} ".
