وَعَنْ طَاوُسٍ، عَنِ اِبْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«لَا تَلَقَّوْا اَلرُّكْبَانَ، وَلَا يَبِيعُ حَاضِرٌ لِبَادٍ. قُلْتُ لِابْنِ عَبَّاسٍ: مَا قَوْلُهُ: «وَلَا يَبِيعُ حَاضِرٌ لِبَادٍ? «قَالَ: لَا يَكُونُ لَهُ سِمْسَارًا»
“Do not go out to meet riders (to conduct business with them), and a city-dweller must not sell for a man from the desert.” I asked Ibn Abbas (radiyallahu anhu), “What did he mean by ‘A city-dweller must not sell for a man from the desert.’” He replied, “He should not act as a broker for him.”.
