Hadith text
Narrated Abu Huraira:I said: "O Allah's Messenger (ﷺ)! Who will be the luckiest person, who will gain your intercession on the Day of Resurrection?" Allah's Messenger (ﷺ) said: "O Abu Huraira! I have thought that none will ask me about it before you as I know your longing for the (learning of) Hadiths. The luckiest person who will have my intercession on the Day of Resurrection will be the one who said sincerely from the bottom of his heart "None has the right to be worshipped but Allah
Abu Huraira (رضی اللہ عنہ) bataate hain: "Maine pucha: 'Ya Rasoolallah! Qiyamat ke din sabse khush-naseeb kaun hoga jise aapki shifa'at milegi?' Allah ke Rasool (ﷺ) ne farmaya: 'Aye Abu Huraira! Mujhe pata tha ke yeh sawaal tumse pehle koi nahi poochega, kyunke main jaanta hoon tumhe hadith seekhne ka kitna shauq hai. Qiyamat ke din sabse khush-naseeb jise meri shifa'at milegi, woh hoga jisne apne dil ki gehraiyon se sacche dil se kaha: La ilaha illallah.'"
