Abu Hurayrah accepted Islam in the year of Khaybar — long after many other Companions. Yet more hadith reached us through him than through anyone else.
❝ HadithAbu Hurayrah said: people say Abu Hurayrah narrates a great deal. Were it not for two verses in Allah's Book I would not narrate a single hadith — those who conceal the clear signs Allah sent down are warned. Our brothers of the Muhajirun were busy trading in the markets, and our brothers of the Ansar with their lands. And Abu Hurayrah stayed close to the Messenger of Allah ﷺ, content with enough to fill his stomach; he was present where they were not, and memorised what they did not.Sahih al-Bukhari 118 · Sahih
إِنَّ ٱلَّذِينَ يَكۡتُمُونَ مَآ أَنزَلۡنَا مِنَ ٱلۡبَيِّنَٰتِ وَٱلۡهُدَىٰ مِنۢ بَعۡدِ مَا بَيَّنَّٰهُ لِلنَّاسِ فِي ٱلۡكِتَٰبِ أُوْلَٰٓئِكَ يَلۡعَنُهُمُ ٱللَّهُ وَيَلۡعَنُهُمُ ٱللَّٰعِنُونَ
“Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture - those are cursed by Allāh and cursed by those who curse,”
Surah Al-Baqarah 2:159
