Yahya related to me from Malik from Abdullah ibn Abi Bakr ibn Muhammad ibn Amr ibn Hazm that Aban ibn Uthman and Hisham ibn Ismail used to mention in their khutbas built-in liability agreements in the sale of slaves, to cover both a three day period and a similar clause covering a year. Malik explained, "The defects a lave or slave-girl are found to have from the time they are bought until the end of the three days are the responsibility of the seller. The year agreement is to cover insanity, leprosy, and loss of limbs due to disease. After a year, the seller is free from any liability." Malik said,"An inheritor or someone else who sells a slave or slave-girl without any such built-in guarantee is not responsible for any fault in the slave and there is no liability agreement held against him unless he was aware of a fault and concealed it. If he was aware of a fault, the lack of guarantee does not protect him. The purchase is returned. In our view, built-in liability agreements only apply to the purchase of slaves."
