Sahih Adab al-Mufrad

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "O Banu Salamah, who is your chief?" We replied: Jad bin Qais, although we consider him to be miserly. He said: "What disease can be more destructive than miserliness? Rather, your chief is 'Amr bin Jamuh." In the days of ignorance, 'Amr used to look after their idols, and when the Messenger of Allah (peace and blessings be upon him) would marry, he ('Amr) would arrange the wedding feast on his behalf.

Warrad, the scribe of Sayyiduna Mughirah (may Allah be pleased with him), narrates that Sayyiduna Muawiyah (may Allah be pleased with him) wrote a letter to Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him): "Send me something in writing that you have heard from the Messenger of Allah (peace and blessings be upon him)." So Sayyiduna Mughirah (may Allah be pleased with him) wrote to him. (And in one narration, Warrad said: He dictated to me and I wrote it with my own hand.) Indeed, the Messenger of Allah (peace and blessings be upon him) (and in another narration: I heard from the Messenger of Allah, peace and blessings be upon him) «قيل و قال» (idle talk), wasting wealth, asking too many questions, withholding (people’s rights), and making unlawful demands (i.e., asking for what one is not entitled to, making illegitimate demands), disobedience to mothers, and burying daughters alive.
