I said, "O Allah's Messenger (ﷺ)! Who will be the luckiest person who will gain your intercession on the Dayof Resurrection?" The Prophet (ﷺ) said, "O Abu Huraira! I have thought that none will ask me about thisHadith before you, as I know your longing for the (learning of) Hadiths. The luckiest person who willhave my intercession on the Day of Resurrection will be the one who said, 'None has the right to beworshipped but Allah,' sincerely from the bottom of his heart."
