The Prophet ﷺ forbade two types of business transactions and two ways of dressing. The two types of business transactions are mulamasah and munabadhah. As regards the two ways of dressing, they are the wrapping of the samma', and that when a man wraps himself up in a single garment while sitting in such a way that he does not cover his private parts or there is no garment on his private parts.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ بَيْعَتَيْنِ وَعَنْ لِبْسَتَيْنِ أَمَّا الْبَيْعَتَانِ فَالْمُلاَمَسَةُ وَالْمُنَابَذَةُ وَأَمَّا اللِّبْسَتَانِ فَاشْتِمَالُ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ كَاشِفًا عَنْ فَرْجِهِ أَوْ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ  

Yahya related to me from Malik from Abu'z-Zinad from al-Araj that Abu Hurayra said, "The Messenger of Allah ﷺ forbade two sales. Mulamasa, in which a man is obliged to buy whatever he touches without any choice in the matter, and munabadha, in which two men throw their garment to each other without either seeing the other's garment. He also forbade two ways of dressing. One in which a man sits with his legs drawn up to his chest wrapped in one garment that does not cover his genitals, and the other in which a man wraps a single garment over one arm and shoulder restricting them."  

أَنَّهُ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ لِبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ عَنِ الْمُلاَمَسَةِ وَعَنِ الْمُنَابَذَةِ وَعَنْ أَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ وَعَنْ أَنْ يَشْتَمِلَ الرَّجُلُ بِالثَّوْبِ الْوَاحِدِ عَلَى أَحَدِ شِقَّيْهِ  

[Machine] The Messenger of Allah ﷺ forbade wearing two types of clothing and engaging in two types of transactions. As for the two transactions, they are the simultaneous exchange and the deferred exchange. And as for the two types of clothing, they are the wearing of a shirt over a shirt, and the covering of oneself in a single garment such that nothing is left on his private parts.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ لِبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ أَمَّا الْبَيْعَتَانِ الْمُلَامَسَةُ وَالْمُنَابَذَةُ وَاللِّبْسَتَانِ اشْتِمَالُ الصَّمَّاءِ وَالِاحْتِبَاءُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَيْءٌ  

[Machine] The Prophet Muhammad ﷺ forbade wearing two garments at once, selling two garments as a set, touching and being brushed against, a man wrapping himself in a single garment that has nothing covering his private parts, and a man covering both of his shoulders with a single garment.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ لِبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ عَنِ الْمُلَامَسَةِ وَالْمُنَابَذَةِ وَعَنْ أَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَيْءٌ وَعَنْ أَنْ يَشْتَمِلَ الرَّجُلُ بِالثَّوْبِ الْوَاحِدِ عَلَى أَحَدِ شِقَّيْهِ  

"عَنْ طَاوُوسٍ قَال: نَهَى رَسُولُ اللَّهِ ﷺ : عَنْ لُبْسَتَينِ وَعَنْ بَيعَتَينِ، أَمَّا اللُّبْسَتَانِ فَاشْتِمَالُ الصَّمَّاءِ وَأنْ يَحْتَبِى فِى ثَوْبٍ وَاحِدٍ مُفْضِيًا بِفَرْجِهِ إِلَى السَّمَاءِ، وَأَمَّا البَيعَتَانِ: فَالمُنَابَذَةُ وَالمُلامَسَةُ".
