Sahih Muslim , Book 31, Hadith 5901 (USC-MSA) ⓘ
A'isha reported Allah's Messenger as saying: There had been among the people before you inspired persons and if there were any such among my Umma Umar b. Khattab would be one of them. Ibn Wahb explained the word Muhaddathun as those who receive hint from the High (Mulhamun).
حَدَّثَنِي أَبُو الطَّاهِرِ، أَحْمَدُ بْنُ عَمْرِو بْنِ سَرْحٍ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، عَنْ إِبْرَاهِيمَ، بْنِ سَعْدٍ عَنْ أَبِيهِ، سَعْدِ بْنِ إِبْرَاهِيمَ عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ يَقُولُ " قَدْ كَانَ يَكُونُ فِي الأُمَمِ قَبْلَكُمْ مُحَدَّثُونَ فَإِنْ يَكُنْ فِي أُمَّتِي مِنْهُمْ أَحَدٌ فَإِنَّ عُمَرَ بْنَ الْخَطَّابِ مِنْهُمْ " . قَالَ ابْنُ وَهْبٍ تَفْسِيرُ مُحَدَّثُونَ مُلْهَمُونَ .
