Sahih al-Bukhari, Volume 4, Book 56, Hadith 675 (USC-MSA) ⓘ
Narrated Abu Huraira: The Prophet said, "Amongst the people preceding you there used to be 'Muhaddithun' (i.e. persons who can guess things that come true later on, as if those persons have been inspired by a divine power), and if there are any such persons amongst my followers, it is `Umar bin Al-Khattab."
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ أَبِيهِ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّهُ قَدْ كَانَ فِيمَا مَضَى قَبْلَكُمْ مِنَ الأُمَمِ مُحَدَّثُونَ، وَإِنَّهُ إِنْ كَانَ فِي أُمَّتِي هَذِهِ مِنْهُمْ، فَإِنَّهُ عُمَرُ بْنُ الْخَطَّابِ " .
