It was narrated from ‘Abdullah (رضي الله عنه) that

One of the things that the Prophet (ﷺ) often said was "Glory and praise be to You our Lord’ O Allah forgive me." When the soorah "When there comes the Help of Allah (to you, O Muhammad (ﷺ) against your enemies) and the Conquest (of Makkah)" (an-Nasr 110:1) was revealed, he said: “Glory and praise be to You, O Allah our Lord. O Allah, forgive me, for You are the Acceptor of repentance, the Most Merciful."
