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 Messenger of Allah 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.

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا عَبْدَةُ، حَدَّثَنَا هِشَامٌ، عَنْ فَاطِمَةَ، عَنْ
أَسْمَاءَ، جَاءَتِ امْرَأَةٌ إِلَى النَّبِيِّ ﷺ فَقَالَتْ إِنَّ لِي ضَرَّةً فَهَلْ عَلَىَّ جُنَاحٌ
أَنْ أَتَشَبَّعَ مِنْ مَالِ زَوْجِي بِمَا لَمْ يُعْطِنِي فَقَالَ رَسُولُ اللَّهِ ﷺ
" الْمُتَشَبِّعُ
بِمَا لَمْ يُعْطَ كَلاَبِسِ ثَوْبَىْ زُورٍ " .
