Jami` at-Tirmidhi, Book 27, Hadith 134 (In-Book) ⓘ
Ibn 'Umar narrated that two men arrived during the time of the Messenger of Allah delivering an address. The people were amazed by their speech, so the Messenger of Allah turned to us and said: "Indeed there is magic in eloquence'-or- 'Indeed some eloquence is magic.'"
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنِ ابْنِ عُمَرَ، أَنَّ رَجُلَيْنِ، قَدِمَا فِي زَمَانِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَخَطَبَا فَعَجِبَ النَّاسُ مِنْ كَلاَمِهِمَا فَالْتَفَتَ إِلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ " إِنَّ مِنَ الْبَيَانِ سِحْرًا " أَوْ " إِنَّ بَعْضَ الْبَيَانِ سِحْرٌ " . قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ عَمَّارٍ وَابْنِ مَسْعُودٍ وَعَبْدِ اللَّهِ بْنِ الشِّخِّيرِ . وَهَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
