ٱسْتَحْوَذَ عَلَيْهِمُ ٱلشَّيْطَٰنُ فَأَنسَىٰهُمْ ذِكْرَ ٱللَّهِ ۚ أُو۟لَٰٓئِكَ حِزْبُ ٱلشَّيْطَٰنِ ۚ أَلَآ إِنَّ حِزْبَ ٱلشَّيْطَٰنِ هُمُ ٱلْخَٰسِرُونَ
The devil hath engrossed them and so hath caused them to forget remembrance of Allah. They are the devil's party. Lo! is it not the devil's party who will be the losers?

Narrated Ibn `Umar:
Two men came from the east and delivered speeches, and the Prophet (ﷺ) said, "Some eloquent speech has the influence of magic." (e.g., some people refuse to do something and then a good eloquent speaker addresses them and then they agree to do that very thing after his speech)
