Abu Huraira reported
The Messenger of Allah (ﷺ) said: The nearest a servant comes to his Lord is when he is prostrating himself, so make supplication (in this state).
Abu Huraira reported
The Messenger of Allah (ﷺ) used to say while prostrating himself: O Lord, forgive me all my sins, small and great, first and last, open and secret.
'A'isha reported
The Messenger of Allah (may peace be upon him') often said while bowing and prostrating himself:" Glory be to Thee, O Allah, our Lord, and praise be to Thee, O Allah, forgive me," thus complying with the (command in) the Qur'an.
'A'isha reported that the Messenger of Allah (ﷺ) before his death recited often
Hallowed be Thou, and with Thy praise, I seek forgiveness from Thee and return to Thee. She reported: I said: Messenger of Allah, what are these words that I find you reciting? He said: There has been made a sign for me in my Ummah; when I saw that, I uttered them (these words of glorification for Allah), and the sign is:" When Allah's help and victory..... to the end of the surah.
'A'isha reported
Never did I, see the Messenger of Allah (ﷺ) after the revelation (of these verses):" When Allah's help and victory came." observin- his prayer without making (this supplication) or he said in it (supplication): Hallowed be Thee, my Lord, and with Thy praise, O Allah, forgive me.
'A'isha reported
The Messenger of Allah (ﷺ) recited often these words: Hallowed be Allah and with His praise, I seek the forgiveness of Allah and return to Him. She said: I asked: Messenger of Allah, I see that you often repeat the saying" subhan allahi bihamdihi astag firullahi watubuilaih" whereupon he said: My Lord informed me that I would soon see a sign in my Ummah, so when I see it I often recite (these) words: Hallowed be Allah and with His Praise, I seek forgiveness of Allah and return to Him. Indeed I saw it (when this verse) was revealed:" When Allah's help and victory came, it marked the victory of Mecca, and you see people entering into Allah's religion in troops, celebrate the praise of Thy Lord and ask His forgiveness. Surely He is ever returning to Mercy."
Ibn Juraij reported
I asked 'Ata': What do you recite when you are in a state of bowing (in prayer)? He said:" Hallowed be Thou, and with Thy praise, there is no god but Thou." Son of Abd Mulaika narrated to me on the anthority of 'A'isha (who reported): I missed one night the Messenger of Allah (ﷺ) (from his bed). I thought that he might have gone to one of his other wives. I searched for him and then came back and (found him) in a state of bowing, or prostration, saying: Hallowed be Thou and with Thy praise; there is no god but Thou. I said: With my father mayest thou be ransomed and with my mother. I was thinking of (another) affair, whereas you are (occupied) in another one.
'A'isha reported
One night I missed Allah's Messenger (ﷺ) from the bed, and when I sought him my hand touched the soles of his feet while he was in the state of prostration; they (feet) were raised and he was saying:" O Allah, I seek refuge in Thy pleasure from Thy anger, and in Thy forgiveness from Thy punishment, and I seek refuge in Thee from Thee (Thy anger). I cannot reckon Thy praise. Thou art as Thou hast lauded Thyself."
'A'isha reported that the Messenger of Allah (may peace he upon him) used to pronounce while bowing and prostrating himself
All Glorious, All Holy, Lord of the Angels and the Spirit.
