Messenger of Allah ﷺ forbade the selling by Munabadha, i.e. to sell one's garment by casting it to the buyer not allowing him to examine or see it. Similarly he forbade the selling by Mulamasa. Mulamasa is to buy a garment, for example, by merely touching it, not looking at it.  

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الْمُنَابَذَةِ وَهْىَ طَرْحُ الرَّجُلِ ثَوْبَهُ بِالْبَيْعِ إِلَى الرَّجُلِ قَبْلَ أَنْ يُقَلِّبَهُ أَوْ يَنْظُرَ إِلَيْهِ وَنَهَى عَنِ الْمُلاَمَسَةِ وَالْمُلاَمَسَةُ لَمْسُ الثَّوْبِ لاَ يَنْظُرُ إِلَيْهِ  

The Prophet ﷺ forbade two kinds of dressing; (one of them) is to sit with one's legs drawn up while wrapped in one garment. (The other) is to lift that garment on one's shoulders. And also forbade two kinds of sale: Al-Limais and An-Nibadh.  

أَنْ يَحْتَبِيَ الرَّجُلُ فِي الثَّوْبِ الْوَاحِدِ ثُمَّ يَرْفَعَهُ عَلَى مَنْكِبِهِ وَعَنْ بَيْعَتَيْنِ اللِّمَاسِ وَالنِّبَاذِ
