عَنْ سَمُرَةَ بْنِ جُنْدُبٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى أَنْ تُتَلَقَّى الْأَجْلَابُ حَتَّى تَبْلُغَ الْأَسْوَاقَ أَوْ يَبِيعَ حَاضِرٌ لِبَادٍ
It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade meeting traders before they reach the markets and that a townsman should sell goods on behalf of a villager.
