Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا شُعْبَةُ عَنْ أَبِي إِسْحَاقَ قَالَ سَمِعْتُ أَبَا عُبَيْدَةَ عَنْ أَبِيهِ قَالَ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُكْثِرُ أَنْ يَقُولَ سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي فَلَمَّا نَزَلَتْ إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ قَالَ سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ التَّوَّابُ.
English Translation
Affan told us, Shu'bah told us, from Abu Ishaq, who said: I heard Abu Ubaydah, from his father, who said: "The Prophet, peace and blessings be upon him, used often to say: 'Glory be to You, O Allah, and praise be to You; O Allah, forgive me.' Then when 'When the victory of Allah has come, and the conquest' was revealed, he would say: 'Glory be to You, O Allah, and praise be to You; O Allah, forgive me; indeed You are the Ever-Relenting.'"
