إِنَّ مِنَ الْبَيَانِ لَسِحْرًا
Translation: Some eloquent speech has an effect like magic.
Source: البخاري
Words can strongly affect people’s feelings, decisions, and opinions. Clear and expressive language can explain truth well; the same skill can also mislead when used dishonestly. Eloquence therefore requires truthfulness and goodwill.
مِنَ الْبَيَانِ means “some forms of speech.” إِنَّ adds emphasis, and the prefixed لَـ in لَسِحْرًا reinforces it. The comparison to magic illustrates unusual persuasive power; it is not a literal claim that all fine speaking is sorcery.
Good speaking should clarify the evidence rather than replace it.
