Musnad Ahmad 295:3

Ibn Numayr narrated to us, he said: Hisham narrated to us, from his father, from Abdullah ibn Zam'ah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) delivered a sermon, and he mentioned the she-camel, and he mentioned the one who hamstrung it. He said: "{When the most wretched of them was sent forth} [Ash-Shams: 12], a man who was wicked, powerful, and protected among his clan was sent forth for it, like Ibn Zam'ah." Then he mentioned women and exhorted them regarding them, and said: "Why does one of you whip his wife as one whips a slave, when he might lie with her at the end of his day?" Then he exhorted them regarding their laughing at a fart, and said: "Why does one of you laugh at what he does himself?"
