[Machine] The Messenger of Allah ﷺ forbade wearing of two garments and the sale of two garments. As for the wearing of two garments, it encompasses the wearing of a garment that has both ends placed on his left shoulder, while its opening is over his right shoulder. The other is wearing a single garment that has nothing else on it, and he lets down his lower garment area up towards the sky. As for the sale of two garments, it includes throwing away and relinquishing a garment, where he says, "If you throw away this garment, the sale is binding." And the contact means touching it with his hand without wearing or flipping it, and if he touches it, the sale becomes binding.
نَهَى رَسُولُ اللهِ ﷺ عَنْ لِبْسَتَيْنِوَعَنْ بَيْعَتَيْنِ أَمَّا اللِّبْسَتَانِ فَاشْتِمَالُ الصَّمَّاءِ أَنْ يَشْتَمِلَ فِي ثَوْبٍ وَاحِدٍ يَضَعَ طَرَفَيِ الثَّوْبِ عَلَى عَاتِقِهِ الْأَيْسَرِ وَيَتَّزِرَ بِشِقِّهِ الْأَيْمَنِ وَالْأُخْرَى أَنْ يَحْتَبِيَ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَيْهِ غَيْرُهُ وَيُفْضِيَ بِفَرْجِهِ إِلَى السَّمَاءِ وَأَمَّا الْبَيْعَتَانِ فَالْمُنَابَذَةُ وَالْمُلَامَسَةُ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتَ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلَامَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلَا يَلْبَسَهُ وَلَا يُقَلِّبَهُ إِذَا مَسَّهُ وَجَبَ الْبَيْعُ
