The Messenger of Allah ﷺ said: Allah , the Exalted, hates the eloquent one among men who moves his tongue round (among his teeth), as cattle do. (Using translation from Abū Dāʾūd 5005)
"إِنَّ الله يُبْغِضُ الْبَليِغَ مِنَ الرِّجَالِ الَّذِي يَتَخَلَّل بِلسَانِه كما يَتَخَلَّلُ الْبَاقِرَةُ بِلِسَانها".
