Mishkat al-Masabih, 3247

Asma’ told of a woman who said, “Messenger of God, 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 the two garments of falsehood.” (Bukhari and Muslim.)

وَعَنْ أَسْمَاءَ أَنَّ امْرَأَةً قَالَتْ: يَا رَسُولَ اللَّهِ إِنَّ لِي ضَرَّةً فَهَلْ عَلَيَّ جُنَاحٌ إِنْ تَشَبَّعْتُ مِنْ زَوْجِي غَيْرَ الَّذِي يُعْطِينِي؟ فَقَالَ: «الْمُتَشَبِّعُ بِمَا لَمْ يُعْطَ كَلَابِسِ ثَوْبَيْ زُورٍ»
