A'isha reported that a woman said
Allah's Messenger, may I say to my (co-wife) that my husband has given me (such and such) a thing but which he has not in fact gives me? 'Thereupon Allah's Messenger (ﷺ) said: The one who makes a false statement of that which one has not been given is like one who wears a garment of falsehood.
Asma' reported that a woman came to Allah's Apostle (ﷺ) 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 Allah's Messenger (ﷺ) 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.
