Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَنْ إِسْرَائِيلَ عَنْ أَبِي إِسْحَاقَ عَنْ أَبِي عُبَيْدَةَ عَنْ عَبْدِ اللَّهِ قَالَ لَمَّا أُنْزِلَ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ كَانَ يُكْثِرُ إِذَا قَرَأَهَا وَرَكَعَ أَنْ يَقُولَ سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ التَّوَّابُ الرَّحِيمُ ثَلَاثًا.
English Translation
Waki’ told us, from Isra’il, from Abu Ishaq, from Abu Ubaydah, from Abdullah, who said: When {When the help of Allah comes and the victory} was sent down upon the Messenger of Allah, peace and blessings be upon him, he would often, when he recited it and bowed and prostrated, say, "Glory be to You, O Allah, our Lord, and praise be to You; O Allah, forgive me; indeed You are the Ever-Relenting, the Merciful" — three times.
