Hadith 4783
عَن ابْن عمر قَالَ: قَدِمَ رَجُلَانِ مِنَ الْمَشْرِقِ فَخَطَبَا فَعَجِبَ النَّاسُ لِبَيَانِهِمَا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ مِنَ الْبَيَانِ لَسِحْرًا» . رَوَاهُ البُخَارِيّ
Ibn Umar (may Allah be pleased with him) narrates: Two men came from the east and addressed (the people). The people were amazed at their speech, so the Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, some speech has the effect of magic." Narrated by al-Bukhari.
