Hadith 43:225
Asma’, daughter of Abu Bakr, told of a woman who said :
Messenger of Allah! I have a fellow-wife; will it be wrong for me to boast of receiving from my husband what he does not give me? He replied: the one who boasts of receiving what he has not been given is like him who has put on two garments of falsehood.
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ بِنْتِ الْمُنْذِرِ، عَنْ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ، أَنَّ امْرَأَةً، قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ لِي جَارَةً - تَعْنِي ضَرَّةً - هَلْ عَلَىَّ جُنَاحٌ إِنْ تَشَبَّعْتُ لَهَا بِمَا لَمْ يُعْطِ زَوْجِي قَالَ " الْمُتَشَبِّعُ بِمَا لَمْ يُعْطَ كَلاَبِسِ ثَوْبَىْ زُورٍ "
