قُلْتُ لأَبِي أُسَامَةَ أَحَدَّثَكُمْ عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ نَهَى رَسُولُ اللَّهِ ﷺ عَنْ تَلَقِّي الْجَلَبِ حَتَّى يَدْخُلَ بِهَا السُّوقَ فَأَقَرَّ بِهِ أَبُو أُسَامَةَ وَقَالَ نَعَمْ

"The Messenger of Allah said: 'Do and whoever meets any of them and buys from him the vendor has the choice of annulling the transaction when he comes to the marketplace."'  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَلَقُّوا الْجَلَبَ فَمَنْ تَلَقَّاهُ فَاشْتَرَى مِنْهُ فَإِذَا أَتَى سَيِّدُهُ السُّوقَ فَهُوَ بِالْخِيَارِ

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

And he said that Mulamasah means when one man says to another: "I will sell you my garment for your garment," and neither of them looks at the garment of the others, rather he just touches it. And Munabadhah is when he says: "I will throw what I have and you throw what you have," so that they buy from one another, and neither of them knows how much the other has, and so on.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ نَهَى عَنْ بَيْعَتَيْنِ أَمَّا الْبَيْعَتَانِ فَالْمُنَابَذَةُ وَالْمُلاَمَسَةُ وَزَعَمَ أَنَّ الْمُلاَمَسَةَ أَنْ يَقُولَ الرَّجُلُ لِلرَّجُلِ أَبِيعُكَ ثَوْبِي بِثَوْبِكَ وَلاَ يَنْظُرَ وَاحِدٌ مِنْهُمَا إِلَى ثَوْبِ الآخَرِ وَلَكِنْ يَلْمِسُهُ لَمْسًا وَأَمَّا الْمُنَابَذَةُ أَنْ يَقُولَ أَنْبُذُ مَا مَعِي وَتَنْبُذُ مَا مَعَكَ لِيَشْتَرِيَ أَحَدُهُمَا مِنَ الآخَرِ وَلاَ يَدْرِي كُلُّ وَاحِدٍ مِنْهُمَا كَمْ مَعَ الآخَرِ وَنَحْوًا مِنْ هَذَا الْوَصْفِ
