"What does a town-dweller (selling) for a desert-dweller mean?" he said: "He should not act as a broker for him," (Using translation from Nasāʾī 4500)
نَهَى النَّبِيُّ ﷺ أَنْ يُتَلَقَّى الرُّكْبَانُ وَأَنْ يَبِيعَ حَاضِرٌ لِبَادٍ قُلْتُ لِابْنِ عَبَّاسٍ مَا قَوْلُهُ لَا يَبِيعُ حَاضِرٌ لِبَادٍ؟ قَالُوا لَا يَكُونُ لَهُ سِمْسَارًا
