Hadith 1306B1

قَالَ مَالِك : الْأَمْرُ الْمُجْتَمَعُ عَلَيْهِ عِنْدَنَا : أَنَّ كُلَّ مَنِ ابْتَاعَ وَلِيدَةً فَحَمَلَتْ، أَوْ عَبْدًا فَأَعْتَقَهُ، وَكُلَّ أَمْرٍ دَخَلَهُ الْفَوْتُ حَتَّى لَا يُسْتَطَاعَ رَدُّهُ، فَقَامَتِ الْبَيِّنَةُ إِنَّهُ قَدْ كَانَ بِهِ عَيْبٌ عِنْدَ الَّذِي بَاعَهُ، أَوْ عُلِمَ ذَلِكَ بِاعْتِرَافٍ مِنَ الْبَائِعِ أَوْ غَيْرِهِ، فَإِنَّ الْعَبْدَ أَوِ الْوَلِيدَةَ يُقَوَّمُ وَبِهِ الْعَيْبُ الَّذِي كَانَ بِهِ يَوْمَ اشْتَرَاهُ، فَيُرَدُّ مِنَ الثَّمَنِ قَدْرُ مَا بَيْنَ قِيمَتِهِ صَحِيحًا، وَقِيمَتِهِ وَبِهِ ذَلِكَ الْعَيْبُ .
Imam Malik, may Allah have mercy on him, said: In our view, this issue is agreed upon that if a person buys a slave-girl, then she becomes pregnant by the buyer, or buys a slave and then sets him free, or does any other act due to which the slave or slave-girl cannot be returned, and after that witnesses testify that there was a defect in this slave or slave-girl while with the seller, or the seller himself admits that this defect was present with me, or it becomes known by any other means that the defect was indeed with the seller, then the price should be set for the slave or slave-girl including the defect as on the day of purchase, and also the price of a sound (defect-free) one should be set; the difference between the two prices, that much the buyer should recover from the seller.
