Sahih Muslim · Hadith 5706

حدثنا محمد بن عبد الله بن نمير، حدثنا عبدة، حدثنا هشام، عن فاطمة، عن أسماء، جاءت امرأة إلى النبي صلى الله عليه وسلم فقالت إن لي ضرة فهل على جناح أن أتشبع من مال زوجي بما لم يعطني فقال رسول الله صلى الله عليه وسلم ‏"‏ المتشبع بما لم يعط كلابس ثوبى زور ‏"‏ ‏.‏

Is there any harm for me if I give her the false impression (of getting something from my husband which he has not in fact given me)? Thereupon Allah's Messenger (may peace be upon him) said: The one who creates such a (false impression) of receiving what one has not been given is like one who wears the garment of falsehood.
