باب النَّهْىِ عَنِ التَّزْوِيرِ، فِي اللِّبَاسِ وَغَيْرِهِ وَالتَّشَبُّعِ بِمَا لَمْ يُعْطَ ‏.‏
Sahih Muslim 2129

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.
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا وَكِيعٌ، وَعَبْدَةُ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، أَنَّ امْرَأَةً، قَالَتْ يَا رَسُولَ اللَّهِ أَقُولُ إِنَّ زَوْجِي أَعْطَانِي مَا لَمْ يُعْطِنِي فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ الْمُتَشَبِّعُ بِمَا لَمْ يُعْطَ كَلاَبِسِ ثَوْبَىْ زُورٍ ‏"‏ ‏.‏
