' Aishah (May Allah be pleased with her) said:
After the revelation of (the Surah) "When the Help of Allah comes (to you, O Muhammad ﷺ against your enemies) and the Conquest (of Makkah)" (110:1), Messenger of Allah ﷺ used to recite in every prayer: "Subhanaka Rabbana wa bihamdika, Allahum-maghfir li (Far removed You are from every imperfection, our Rubb, and all praise is for You, forgive me, O Allah)".

[Al-Bukhari and Muslim].

Another narration is: Messenger of Allah ﷺ recited frequently in bowing and prostration: "Subhanaka Rabbana wa bihamdika, Allahum-maghfir li. (Far removed You are from every imperfection, our Rubb, and all praise is for You, forgive me, O Allah)". He elucidated that it has been commanded in the Noble Qur'an to recite: "So glorify the Praises of your Rubb, and ask for His forgiveness. Verily, He is the One Who accepts the repentance and Who forgives". (V.110:1) And he (the Messenger of Allah) acted upon it.

According to the narration in Muslim, Messenger of Allah ﷺ frequently recited these words just before he passed away: "Subhanaka Rabbana wa bihamdika. Astaghfiruka wa atubu ilaika." I ('Aishah (May Allah be pleased with her) asked him: "O Messenger of Allah! What are these new words which I hear from you repeatedly." He replied, "A sign has been appointed for me relating to my people that I should repeat these words at the sight of that sign". Then he recited Surat An-Nasr.

Another narration in Muslim related from 'Aishah (May Allah be pleased with her) is: Messenger of Allah ﷺ often recited, "Glory be to Allah and praise be to Him; I seek forgiveness of Allah and turn to Him in repentance." I said to him: "O Messenger of Allah, I hear you recite frequently: 'O Allah, You are free from every imperfection our Rubb and all praise is for You; I seek forgiveness of Allah and turn to Him in repentance."' He replied, "My Rubb has informed me that I would soon see a sign regarding my people, whenever I see it, I repeat this statement more often (of His Glorification and Praise and beg pardon of Him and turn to Him). Now I have witnessed the sign. The revelation of Surat An-Nasr and the victory is the conquest of Makkah."

"When there comes the Help of Allah (to you, O Muhammad ﷺ against your enemies) and the Conquest (of Makkah). And you see that the people enter Allah's religion (Islam) in crowds. So glorify the Praises of your Rubb, and ask His forgiveness. Verily, He is the One Who accepts the repentance and Who forgives." (110:1-3)

الثالث: عن عائشة رضي الله عنها قالت: ما صلى رسول الله ﷺ صلاة بعد أن نزلت عليه { إذا جاء نصر الله والفتح} إلا يقول فيها: " سبحانك ربنا وبحمدك، اللهم اغفر لي" ((متفق عليه)). وفي رواية في الصحيحين" عنها: كان رسول الله ﷺ يكثر أن يقول في ركوعه وسجوده: "سبحانك اللهم ربنا وبحمدك، اللهم اغفر لي" يتأول القرآن.وفي رواية لمسلم: كان رسول الله ﷺ يكثر أن يقول قبل أن يموت: "سبحانك اللهم وبحمدك، أستغفرك وأتوب إليك". قالت عائشة: قلت: يا رسول الله ما هذه الكلمات التي أراك أحدثتها تقولها؟ قال: "جعلت لي علامة في أمتي إذا رأيتها قلتها {إذا جاء نصر الله والفتح} إلى آخر السورة".وفي رواية له: كان رسول الله ﷺ يكثر من قول: "سبحان الله وبحمده، أستغفر الله وأتوب إليه". قالت: قلت: يا رسول الله! أراك تكثر من قول: سبحان الله وبحمده، أستغفر الله وأتوب إليه؟ فقال: "أخبرني ربي أني سأرى علامة في أمتي فإذا رأيتها أكثرت من قول: سبحان الله وبحمده، أستغفر الله وأتوب إليه، فقد رأيتها: {إذا جاء نصر الله والفتح} فتح مكة، {ورأيت الناس يدخلون في دين الله أفواجاً، فسبح بحمد ربك واستغفره إنه كان تواباً}.
