Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ آدَمَ حَدَّثَنَا إِسْرَائِيلُ عَنْ أَبِي إِسْحَاقَ عَنْ أَبِي عُبَيْدَةَ عَنْ عَبْدِ اللَّهِ قَالَ مُنْذُ أُنْزِلَ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ كَانَ يُكْثِرُ أَنْ يَقُولَ إِذَا قَرَأَهَا ثُمَّ رَكَعَ بِهَا أَنْ يَقُولَ سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ التَّوَّابُ الرَّحِيمُ ثَلَاثًا.
English Translation
Yahya ibn Adam told us, Isra'il told us, from Abu Ishaq, from Abu Ubaydah, from Abdullah, who said: Ever since "When the help of Allah and the victory come" was revealed to the Messenger of Allah, peace and blessings be upon him, he used often, when he recited it and then bowed [in prayer] with it, to say: "Glory be to You, our Lord, and praise be to You; O Allah, forgive me, for indeed You are the Ever-Relenting, the Merciful" - three times.
