‘Abd Allah b. ‘Umar said :
When two men who came from the east made a speech and the people were charmed with their eloquence, the Messenger of Allah ﷺ said: In some eloquent speech there is magic.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ قَدِمَ رَجُلاَنِ مِنَ الْمَشْرِقِ فَخَطَبَا فَعَجِبَ النَّاسُ - يَعْنِي لِبَيَانِهِمَا - فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ مِنَ الْبَيَانِ لَسِحْرًا " . أَوْ " إِنَّ بَعْضَ الْبَيَانِ لَسِحْرٌ " .
