Hadith 809

Narrated [Abu Hurairah (RA)]: Allah's Messenger (SAW) forbade, a city-dweller to sell for a man from the desert; one to bid against another (to raise the price); that someone sell (his product) by canceling the sale of his brother; to propose (marriage) to a woman after his brother has done so; or a woman to ask to have her sister divorced in order to deprive her of what belongs to her. [Agreed upon].

وَعَنْهُ قَالَ: { نَهَى رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-أَنْ يَبِيعَ حَاضِرٌ لِبَادٍ, وَلَا تَنَاجَشُوا, وَلَا يَبِيعُ اَلرَّجُلُ عَلَى بَيْعِ أَخِيهِ, وَلَا يَخْطُبُ عَلَى خِطْبَةِ أَخِيهِ, وَلَا تُسْأَلُ اَلْمَرْأَةُ طَلَاقَ أُخْتِهَا لِتَكْفَأَ مَا فِي إِنَائِهَا } مُتَّفَقٌ عَلَيْهِ <sup>1</sup>‏ .‏
