Arabic (Original)
حَدَّثَنَا سُلَيْمَانُ أَنْبَأَنَا إِسْمَاعِيلُ أَخْبَرَنِي عَمْرٌو عَنْ سَعِيدٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قُلْتُ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ أَسْعَدُ النَّاسِ بِشَفَاعَتِكَ يَوْمَ الْقِيَامَةِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَقَدْ ظَنَنْتُ يَا أَبَا هُرَيْرَةَ أَلَّا يَسْأَلَنِي عَنْ هَذَا الْحَدِيثِ أَحَدٌ أَوَّلَ مِنْكَ لِمَا رَأَيْتُ مِنْ حِرْصِكَ عَلَى الْحَدِيثِ أَسْعَدُ النَّاسِ بِشَفَاعَتِي يَوْمَ الْقِيَامَةِ مَنْ قَالَ لَا إِلَهَ إِلَّا اللَّهُ خَالِصَةً مِنْ قِبَلِ نَفْسِهِ.
English Translation
I said to the Prophet (peace be upon him): 'Who is the most fortunate of people to receive your intercession on the Day of Resurrection?' The Prophet (peace be upon him) said: 'I thought, O Abu Hurayrah, that no one would ask me about this hadith before you, because of what I have seen of your eagerness for hadith. The most fortunate of people to receive my intercession on the Day of Resurrection is the one who says La ilaha illallah (there is no god but Allah) sincerely from his heart.'
