Musnad Ahmad 950:0

Sa’id ibn Sa’d ibn ‘Ubadah reported: The Messenger of Allah (ﷺ) said: "If there were to be a successor for anyone to prostrate to another, I would have commanded the woman to prostrate to her husband, due to the greatness of his right over her. And a woman would not find the sweetness of faith until she fulfills the right of her husband, even if he were to call her while she is upon the saddle of a camel."
