وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ قَالَ لاَ رِبًا فِي الْحَيَوَانِ وَإِنَّمَا نُهِيَ مِنَ الْحَيَوَانِ عَنْ ثَلاَثَةٍ عَنِ الْمَضَامِينِ وَالْمَلاَقِيحِ وَحَبَلِ الْحَبَلَةِ ‏.‏ وَالْمَضَامِينُ بَيْعُ مَا فِي بُطُونِ إِنَاثِ الإِبِلِ وَالْمَلاَقِيحُ بَيْعُ مَا فِي ظُهُورِ الْجِمَالِ ‏.‏ قَالَ مَالِكٌ لاَ يَنْبَغِي أَنْ يَشْتَرِيَ أَحَدٌ شَيْئًا مِنَ الْحَيَوَانِ بِعَيْنِهِ إِذَا كَانَ غَائِبًا عَنْهُ وَإِنْ كَانَ قَدْ رَآهُ وَرَضِيَهُ عَلَى أَنْ يَنْقُدَ ثَمَنَهُ لاَ قَرِيبًا وَلاَ بَعِيدًا ‏.‏ قَالَ مَالِكٌ وَإِنَّمَا كُرِهَ ذَلِكَ لأَنَّ الْبَائِعَ يَنْتَفِعُ بِالثَّمَنِ وَلاَ يُدْرَى هَلْ تُوجَدُ تِلْكَ السِّلْعَةُ عَلَى مَا رَآهَا الْمُبْتَاعُ أَمْ لاَ فَلِذَلِكَ كُرِهَ ذَلِكَ وَلاَ بَأْسَ بِهِ إِذَا كَانَ مَضْمُونًا مَوْصُوفًا ‏.‏

Yahya related to me from Malik from Ibn Shihab that Said ibn al-Musayyab said, "There is no usury in animals. There are three thingsforbidden in animals: al-madamin, al-malaqih and habal al-habala. Al-madamin is the sale of what is in the wombs of female camels. Al-malaqih is the sale of the breeding qualities of camels" (i.e. forstud). Malik said, "No one should buy a specified animal whenit is concealed from him or in another place, even if he has alreadyseen it, very recently or not so recently, and was pleased enough withit to pay its price in cash." Malik said, "That isdisapproved of because the seller makes use of the price and it is notknown whether or not those goods are found to be as the buyer saw themor not. For that reason, it is disapproved of. There is no harm in itif it is described and guaranteed." Translation Not Available
