Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: A Bedouin came to the Messenger of Allah (peace and blessings be upon him) and began to speak in clear, eloquent words. So the Messenger of Allah (peace and blessings be upon him) said: "Some eloquence is magic, and some poetry is wisdom."
