أَنْ يَبِيعَ حَاضِرٌ لِبَادٍ وَإِنْ كَانَ أَخَاهُ أَوْ أَبَاهُ  

"It was forbidden to us for a town-dweller to sell for a desert-dweller, even if he was his father or brother." (Sahih )

Malik said: It was said: A townsman must not sell for a man from the desert. This phrase carries a broad meaning. It means that the (the townsman) must not sell anything for him or buy anything for him.
