It is forbidden to meet the caravans on the way (to buy the goods away from the market)
Arabic hadith text
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 صلى الله عليه وسلم عَنْتَلَقِّي الْبُيُوعِ.
Translation
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 (ﷺ) forbade meeting the owners of goods on the way away from the market.
