It is narrated from Hazrat Asma that a woman came to the service of the Prophet (peace be upon him) and said, "O Messenger of Allah, I have a co-wife. If my husband has not given me anything, but I pretend that he has provided me with such and such a thing, will there be any sin upon me for this?" The Prophet (peace be upon him) said, "To pretend to have received something which one has not been given is like wearing two garments of falsehood."
