It is forbidden to meet the caravans on the way (to buy the goods away from the market)

Narrated Abu Huraira:

The Prophet forbade the meeting (of caravans) on the way and the selling of goods by an inhabitant of the town on behalf of a desert dweller.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ نَهَى النَّبِيُّ ﷺ عَنِ التَّلَقِّي، وَأَنْ يَبِيعَ حَاضِرٌ لِبَادٍ.

Narrated Tawus:

I asked Ibn 'Abbas, "What is the meaning of, 'No town dweller should sell (or buy) for a desert dweller'?" Ibn 'Abbas said, "It means he should not become his broker."

حَدَّثَنِي عَيَّاشُ بْنُ الْوَلِيدِ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا مَعْمَرٌ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ مَا مَعْنَى قَوْلِهِ " لاَ يَبِيعَنَّ حَاضِرٌ لِبَادٍ ". فَقَالَ لاَ يَكُنْ لَهُ سِمْسَارًا.

Narrated Abdullah:

Whoever buys an animal which has been kept unmilked for a long time, could return it, but has to pay a Sa of dates along with it. And the Prophet forbade meeting the owners of goods on the way away from the market.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، قَالَ حَدَّثَنِي التَّيْمِيُّ، عَنْ أَبِي عُثْمَانَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ مَنِ اشْتَرَى مُحَفَّلَةً فَلْيَرُدَّ مَعَهَا صَاعًا. قَالَ وَنَهَى النَّبِيُّ ﷺ عَنْ تَلَقِّي الْبُيُوعِ.
