"The Messenger of Allah forbade two kinds of garments and two kinds of transactions. As for the two kinds of transactions, they are Mulamash and Munabadhaha. Munabadha is when a man says, 'I throw this garment, and the transaction becomes binding, and Mulamasah is when a man touches it with his had, without spreading it out and checking it, and once he touches it, the transaction becomes binding."  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ لُبْسَتَيْنِ وَعَنْ بَيْعَتَيْنِ أَمَّا الْبَيْعَتَانِ فَالْمُلاَمَسَةُ وَالْمُنَابَذَةُ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتُ هَذَا الثَّوْبَ فَقَدْ وَجَبَ يَعْنِي الْبَيْعَ وَالْمُلاَمَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلاَ يَنْشُرَهُ وَلاَ يُقَلِّبَهُ إِذَا مَسَّهُ فَقَدْ وَجَبَ الْبَيْعُ  

"Wearing the samma' means that a man puts his garment over his left shoulder and keeps his right side uncovered. Munabadhah means that a man says (to another): If I throw this garment to you, the sale will be certain. Mulamasah means that a man touches it (another's garment) with his hand and neither he unfolds it nor turns it over. When he touched it, the sale becomes binding.  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ زَادَ وَاشْتِمَالُ الصَّمَّاءِ أَنْ يَشْتَمِلَ فِي ثَوْبٍ وَاحِدٍ يَضَعُ طَرَفَىِ الثَّوْبِ عَلَى عَاتِقِهِ الأَيْسَرِ وَيُبْرِزُ شِقَّهُ الأَيْمَنَ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتُ إِلَيْكَ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلاَمَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلاَ يَنْشُرُهُ وَلاَ يُقَلِّبُهُ فَإِذَا مَسَّهُ وَجَبَ الْبَيْعُ  

[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

(Using translation from Nasāʾī 4515)   

«نَهَى رَسُولُ اللَّهِ ﷺ عَنْ بَيْعَتَيْنِ الْمُلَامَسَةِ وَالْمُنَابَذَةِ فَالْمُنَابَذَةُ هُوَ أَنْ يَقُولَ إِذَا نَبَذْتُ إِلَيْكَ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلَامَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلَا يَنْشُرُهُ وَلَا يُقَلِّبُهُ يَقُولُ إِذَا مَسَّهُ وَجَبَ الْبَيْعُ»

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ زَادَ فَاشْتِمَالُ الصَّمَّاءِ يَشْتَمِلُ فِي ثَوْبٍ وَاحِدٍ يَضَعُ طَرَفَيِ الثَّوْبِ عَلَى عَاتِقِهِ الْأَيْسَرِ وَيُبْرِزُ شِقَّهُ الْأَيْمَنَ قَالَ وَالْمُنَابَذَةُ أَنْ يَقُولَ إِذَا نَبَذْتُ هَذَا الثَّوْبَ فَقَدْ وَجَبَ الْبَيْعُ وَالْمُلَامَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلَا يَنْشُرَهُ وَلَا يُقَلِّبَهُ إِذَا مَسَّهُ وَجَبَ الْبَيْعُ  

"نَهَى رَسُولُ الله ﷺ عَنْ بَيْعَتَين، وَعَنْ لُبْسَتَيْنِ، فَأَمَّا اللُّبْسَتَانِ فاشْتِمَالُ الصَّمَاءِ يَشْتَمِلُ فِي ثَوْبٍ وَاحِدٍ، يَضَعُ طَرَفَى الثَّوْبِ عَلَى عَاتِقِهِ الأَيْسَر، وَيُبْرِزُ شِقَّهُ الأَيْمَنَ، وَالآخَرُ أنْ يحْتَبِيَ فِي ثَوْبٍ وَاحِدٍ لَيْسَ عَلَيْهِ غَيرُهُ، يفْضِي بِفَرْجِهِ إلى السَّمَاءِ،

وَأَمَّا البَيْعَتَانِ، فَالْمُنَابَذَةُ وَالمُلَامَسَةُ، وَالْمنَابَذة أَنْ يَقُولَ: إذَا نَبَذْتُ هَذَا الثَّوبَ فَقَدْ وَجَبَ البَيْعُ، وَالمُلَامَسَةُ أَنْ يَمَسَّهُ بِيَدِهِ وَلا يَنْشُرَهُ وَلا يُقَلِّبَهُ إِذَا مَسَّهُ فَقَدْ وَجَبَ البَيْعُ".
