To claim having more things or better qualities than one really has
باب الْمُتَشَبِّعِ بِمَا لَمْ يَنَلْ، وَمَا يُنْهَى مِنِ افْتِخَارِ الضَّرَّةِ

Narrated Asma:
Some lady said, "O Allah's Apostle! My husband has another wife, so it is sinful of me to claim that he has given me what he has not given me (in order to tease her)?" Allah's Apostle ﷺ said, The one who pretends that he has been given what he has not been given, is just like the (false) one who wears two garments of falsehood."
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ هِشَامٍ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ، عَنِ النَّبِيِّ ﷺ. حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، حَدَّثَتْنِي فَاطِمَةُ، عَنْ أَسْمَاءَ، أَنَّ امْرَأَةً، قَالَتْ يَا رَسُولَ اللَّهِ إِنَّ لِي ضَرَّةً، فَهَلْ عَلَىَّ جُنَاحٌ إِنْ تَشَبَّعْتُ مِنْ زَوْجِي غَيْرَ الَّذِي يُعْطِينِي فَقَالَ رَسُولُ اللَّهِ ﷺ " الْمُتَشَبِّعُ بِمَا لَمْ يُعْطَ كَلاَبِسِ ثَوْبَىْ زُورٍ ".
