A woman said, "Messenger of Allah, I have a co-wife. Is there any blame on me if I pretend to be satisfied by my husband with something he has not actually given me?"The Messenger of Allah ﷺ replied, "The one who pretends to have what has not been given to him is like one who wears two garments of falsehood."
أن امرأة قالت: يا رسول الله، إن لي ضرة، فهل علي جناح إن تشبعت من زوجي غير الذي يعطيني؟ فقال رسول الله ﷺ: المتشبع بما لم يعط كلابس ثوبي زور.
Bukhari narrated it in the Book of Marriage (5219), and Muslim in the Book of Clothing (2130), via Hisham (that is, the son of Urwa), who said, Fatimah (that is, the daughter of Mundhir) narrated to me, from Asma, and he related it.
