Musannaf Ibn Abi Shaybah

Hazrat Ibn Umar (may Allah be pleased with them both) or Hazrat Jabir—one of these two—narrates that there was melodiousness or clarity in the speech of the Messenger of Allah (peace and blessings be upon him).

Hazrat Atiyyah narrates that Hazrat Ibn Umar (may Allah be pleased with them) said: Excessively eloquent speech is like the froth from the mouth of Satan.

Hazrat Aisha (may Allah be pleased with her) narrates that the speech of the Messenger of Allah (peace and blessings be upon him) was so clear that everyone who listened to it would understand it.

Hazrat Abdullah bin Amr (may Allah be pleased with him) narrates in a marfu’ form that Allah, the Lord of Might and Majesty, is hostile towards that person among people who moves his tongue while speaking eloquently, like cattle move their tongues while chewing fodder.

Hazrat Abdul Malik bin Umair narrates that a man stood up and spoke in front of the Holy Prophet (peace and blessings be upon him) until foam came out of his mouth. Upon this, the Holy Prophet (peace and blessings be upon him) said: Learn, and avoid speaking with your mouth wide open, because speaking with your mouth wide open is like the foam that comes out of the mouth of Satan.
