Asma' reported that a woman came to Allaah's Prophet (sallAllaahu alayhi wa sallam) and said: I have a co-wife. 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 Allaah's Messenger (sallAllaahu alayhi wa sallam) 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.
