Darimi

Amr bin Shu'aib narrated from his father, who narrated from his grandfather (Sayyiduna Abdullah bin Amr bin al-As, may Allah be pleased with him), that the Messenger of Allah, peace and blessings be upon him, said: “No one narrates stories (in admonition and advice) except a ruler, or one appointed by the ruler to deliver admonition, or a show-off (who does so to be praised by people for his storytelling).” Abdullah bin Amir said: I heard Amr bin Shu'aib say: We used to hear the name of the one who affects artificiality, so he said: This is what I have heard. (This is his honesty that he narrated exactly as he heard.)
