(35) باب النَّهْىِ عَنِ التَّزْوِيرِ، فِي اللِّبَاسِ وَغَيْرِهِ وَالتَّشَبُّعِ بِمَا لَمْ يُعْطَ .
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 Allah's Messenger (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. (IT)
