When two men who came from the east made a speech and the people were charmed with their eloquence, the Messenger of Allah (May peace be upon him) said: In some eloquent speech there is magic. (Using translation from Abū Dāʾūd 5007)
قَدِمَ رَجُلَانِ مِنَ الْمَشْرِقِ فَخَطَبَا فَعَجِبَ النَّاسُ مِنْ بَيَانِهِمَا فَقَالَ رَسُولُ اللهِ ﷺ إِنَّ بَعْضَ الْبَيَانِ سِحْرٌ أَوْ إِنَّ مِنَ الْبَيَانِ سِحْرًا
