Sunan Ibn Majah 1857

It was narrated from Abu Umamah that:the Prophet used to say: “Nothing is of more benefit to the believer after Taqwa of Allah than a righteous wife whom, if he commands her she obeys him, if he looks at her he is pleased, if he swears an oath concerning her she fulfills it, and when he is away from her she is sincere towards him with regard to herself and his wealth.”
