It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty dislikes the eloquent man who twists his tongue about the way a cow twists (its tongue while gathering fodder)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Abdullah bin Amr (may Allah be pleased with them both) except with this chain; Nafi' bin Umar is alone in narrating it."
