حَدَّثَنَا إِسْمَاعِيلُ قَالَ حَدَّثَنِي مَالِکٌ عَنْ نَافِعٍ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَبِيعُ بَعْضُکُمْ عَلَی بَيْعِ أَخِيهِ
صحیح بخاری · Hadith 2139
Narrated `Abdullah bin `Umar: Allah's Apostle said, "Do not urge somebody to return what he has already bought (i.e. in optional sale) from another seller so as to sell him your own goods."
