Sales and Trade
34/71. Chapter:
It is forbidden to meet the caravans on the way (to buy the goods away from the market)
وَأَنَّ بَيْعَهُ مَرْدُودٌ، لأَنَّ صَاحِبَهُ عَاصٍ آثِمٌ إِذَا كَانَ بِهِ عَالِمًا، وَهُوَ خِدَاعٌ فِي الْبَيْعِ، وَالْخِدَاعُ لاَ يَجُوزُ.And the one who buys them, his bargain is invalid as he is a sinner if he knows it, for it is a kind of deceit, and deceit is forbidden.
Sahih Bukhari
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ، وَلاَ تَلَقَّوُا السِّلَعَ حَتَّى يُهْبَطَ بِهَا إِلَى السُّوقِ ".
Narrated `Abdullah bin `Umar: Allah's Messenger (ﷺ) said, "You should not try to cancel the purchases of one another (to get a benefit thereof), and do not go ahead to meet the caravan (for buying the goods) (but wait) till it reaches the market."
