Asma bint Abu Bakr reported,

A woman came to the Prophet ﷺ and said, "I have a co-wife. Would there be any harm in my pretending to have received more from my husband's wealth than he has actually given me?"The Messenger of Allah ﷺ replied, "The one who pretends to have been given what he has not been given is like someone wearing two garments of falsehood."

Muslim 5585
