Hadith 1375B4

قَالَ مَالِكٌ : وَلَا يَنْبَغِي بَيْعُ الْإِنَاثِ، وَاسْتِثْنَاءُ مَا فِي بُطُونِهَا، وَذَلِكَ أَنْ يَقُولَ الرَّجُلُ لِلرَّجُلِ : ثَمَنُ شَاتِي الْغَزِيرَةِ ثَلَاثَةُ دَنَانِيرَ فَهِيَ لَكَ بِدِينَارَيْنِ، وَلِي مَا فِي بَطْنِهَا، فَهَذَا مَكْرُوهٌ لِأَنَّهُ غَرَرٌ وَمُخَاطَرَةٌ. ¤
Imam Malik, may Allah have mercy on him, said that it is not permissible to sell a female animal and exclude its pregnancy, such as if someone says to another: The price of my milking goat is three dinars, so take it for two dinars, but when the kid in its belly is born, I will take it. This is disliked and not permissible.
