Aisha reported that the Prophet ﷺ used to say frequently in his bowing and prostration, "Glory be to You, Allah our Lord, and praise be to You. Allah, forgive me," following the guidance of the Quran.
قالت: كان النبي ﷺ يكثر أن يقول في ركوعه وسجوده: سبحانك اللهم ربنا وبحمدك، اللهم اغفر لي يتأول القرآن.
Bukhari narrated it in the Tafsir (4968), and Muslim in the Prayer (484), both through Jareer, from Mansur, from Abu Duha, from Masruq, from Ayesha, and he related the hadith. His statement, "interpreting the Quran," contains an allusion to the words of Allah Most High, "When the help of Allah comes and the victory, and you see the people entering into the religion of Allah in multitudes, then glorify your Lord with praise and seek His forgiveness, for He is ever accepting of repentance" [Surah Nasr].In Sahih Bukhari (4967), through Amash, from Abu Duha, from Masruq, from Ayesha, she said, "The Prophet ﷺ never performed a prayer after "When the help of Allah comes and the victory" was revealed to him without saying in it, 'Glory be to You, our Lord, and praise be to You, O Allah forgive me.'"And in Muslim, "I never saw the Prophet ﷺ, from the time "When the help of Allah comes and the victory" was revealed to him, perform a prayer without supplicating, or saying in it, 'Glory be to You, my Lord, and praise be to You, O Allah forgive me.'" He narrated it through Amash with this wording, and he also narrated it through Dawud, from Amir, from Masruq, from Ayesha, who said, "The Messenger of Allah ﷺ used to frequently say, 'Glory be to Allah and praise be to Him, and I seek the forgiveness of Allah and turn to Him in repentance.'" She said, "So I said, 'O Messenger of Allah, I see you frequently saying, "Glory be to Allah and praise be to Him, I seek the forgiveness of Allah and turn to Him in repentance."'" He said, "My Lord informed me that I would see a sign in my nation, and when I saw it, I would frequently say, 'Glory be to Allah and praise be to Him, I seek the forgiveness of Allah and turn to Him in repentance,' and I have now seen it. "When the help of Allah comes and the victory", the conquest of Makkah, "and you see the people entering into the religion of Allah in multitudes, then glorify your Lord with praise and seek His forgiveness, for He is ever accepting of repentance"."
