[Machine] Indeed, the Prophet ﷺ used to frequently say, "Subhanaka Rabbana wa bihamdika Allahumma ighfirli," which means "Glory be to You, our Lord, and praise be to You, O Allah. O Allah, forgive me." He said this when the following verse was revealed: "When comes the help of Allah, and victory, and you see mankind entering the religion of Allah in troops. Celebrate the praises of your Lord, and pray for His forgiveness: for He is Oft-Returning (in forgiveness) and Most Merciful." (Quran 110: 1-3)
أَنَّ النَّبِيَّ ﷺ كَانَ مِمَّا يُكْثِرُ أَنْ يَقُولَ سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ اللهُمَّ اغْفِرْ لِي قَالَ فَلَمَّا نَزَلَتْ إِذَا جَاءَ نَصْرُ اللهِ وَالْفَتْحُ قَالَ سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ اللهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ التَّوَّابُ الرَّحِيمُ
