Malik related to me from Zayd ibn Aslam that Abdullah ibn Umar said, "Two men from the east stood up and spoke, and people were amazed at their eloquence. The Messenger of Allah ﷺ said, 'Some eloquence is sorcery,' or he said, 'Part of eloquence is sorcery.' "
أَنَّهُ قَالَ قَدِمَ رَجُلاَنِ مِنَ الْمَشْرِقِ فَخَطَبَا فَعَجِبَ النَّاسُ لِبَيَانِهِمَا فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ مِنَ الْبَيَانِ لَسِحْرًا أَوْ قَالَ إِنَّ بَعْضَ الْبَيَانِ لَسِحْرٌ
