Musannaf Ibn Abi Shayba 9:1238

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from ‘Amr ibn Yahya ibn Ja‘dah, from the Prophet (may Allah bless him and grant him peace), who said: "The best benefit a Muslim has gained after Islam is a beautiful woman who pleases him when he looks at her, obeys him when he commands her, and protects him regarding her wealth and herself when he is absent from her."
