The Prophet (may Allah's peace and blessings be upon him) did not offer a prayer after the revelation of {When there comes Allah’s help and the conquest} [Surat an-Nasr: 1] except that he would say therein: "Subhānaka Rabbana wa bihamdik, Allāhumma ighfir li (Glory and praise be to You, our Lord. O Allah, forgive me)

عَنْ عَائِشَةَ أُمِّ المُؤْمِنينَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: مَا صَلَّى النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ صَلاَةً بَعْدَ أَنْ نَزَلَتْ عَلَيْهِ: {إِذَا جَاءَ نَصْرُ اللَّهِ وَالفَتْحُ} [النصر: 1] إِلَّا يَقُولُ فِيهَا: «سُبْحَانَكَ رَبَّنَا وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي». وعَنْها قَالَتْ: كَانَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يُكْثِرُ أَنْ يَقُولَ فِي رُكُوعِهِ وَسُجُودِهِ: «سُبْحَانَكَ اللهُمَّ رَبَّنَا وَبِحَمْدِكَ، اللهُمَّ اغْفِرْ لِي» يَتَأَوَّلُ الْقُرْآنَ.

‘Ā’ishah, Mother of the Believers, (may Allah be pleased with her) reported: The Prophet (may Allah's peace and blessings be upon him) did not offer a prayer after the revelation of {When there comes Allah’s help and the conquest} [Surat an-Nasr: 1] except that he would say therein: "Subhānaka Rabbana wa bihamdik, Allāhumma ighfir li (Glory and praise be to You, our Lord. O Allah, forgive me)". She also reported: The Messenger of Allah (may Allah's peace and blessings be upon him) used to say frequently in his Rukū‘ and Sujūd: "Subhānak Allāhumma Rabbana wa bihamdik, Allāhumma ighfir li (Glory and praise be to You, O Allah, our Lord. O Allah, forgive me)" in compliance with the command in the Qur’an.
