Sahih Muslim Book - 37, Hadith - 5584

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ نُمَيْرٍ ، حَدَّثَنَا عَبْدَةُ ، حَدَّثَنَا هِشَامٌ ، عَنْ فَاطِمَةَ ، عَنْ أَسْمَاءَ ، جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَتْ : إِنَّ لِي ضَرَّةً , فَهَلْ عَلَيَّ جُنَاحٌ أَنْ أَتَشَبَّعَ مِنْ مَالِ زَوْجِي بِمَا لَمْ يُعْطِنِي ؟ فَقَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : الْمُتَشَبِّعُ بِمَا لَمْ يُعْطَ ، كَلاَبِسِ ثَوْبَيْ زُورٍ.

It was narrated from Asma' that a woman came to the Prophet (s.a.w) and said: "I have a co-wife; is there any sin on me if I pretend, that my husband has given · me something that he did not give to me?" The Messenger of Allah (s.a.w) said: "The one who pretends to have been given something that he was not given is like the one who wears two garments of falsehood."
