Silsilat al-Ahadith al-Sahihah

Bahz bin Hakim narrates from his father, and he from his grandfather Sayyiduna Mu'awiyah bin Haydah (may Allah be pleased with him), who says: I said, "O Messenger of Allah! From where may a man approach his wife and from where should he not?" The Prophet (peace and blessings be upon him) said: "Approach your field as you wish, and when you eat, feed her as well, and when you clothe yourself, clothe her as well. Do not revile her face, nor strike her upon it."
