Arabic hadith text
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنِي سَالِمُ بْنُ نُوحٍ، قَالَ أَنْبَأَنَا يُونُسُ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَنُهِينَا أَنْ يَبِيعَ، حَاضِرٌ لِبَادٍ وَإِنْ كَانَ أَخَاهُ أَوْ أَبَاهُ .
Translation
It was narrated that Anas bin Malik said
"It was forbidden to us for a town-dweller to sell for a desert-dweller, even if he was his father or brother." (Sahih )
