From Sahih Muslim (Hadith 6812):
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
