Chapter 49: The Book Pertaining to the Remembrance of Allah, Supplication, Repentance and Seeking Forgiveness
Abu Huraira reported Allah' s Messenger (ﷺ) as saying: When one of you makes a supplication (to his Lord) one should not say: O Allah, grant me pardon, if Thou so likest, but one should beg one' s (Lord) with a will and full devotion, for there is nothing so great in the eye of Allah which He cannot grant.
Sahih Muslim 2679a
