A man who buys a slave woman or a slave boy

Al-Sha'bi (may Allah have mercy on him) was asked: If a person buys a slave and frees him, and then the slave turns out to be insane? He (may Allah have mercy on him) said: If this illness existed before the transaction, the seller shall return to the buyer the difference between the value of an insane slave and a sound slave, and he shall put what he has taken toward the like of it.

Al-Hasan said concerning a person who buys a slave and frees him, and then learns that he has an illness that had existed while with the seller: The slave is binding upon him, and it is not obligatory on the seller to return anything.

Al-Zuhri (may Allah have mercy on him) held that the price should be reduced in proportion to the defect when the illness comes to light after the slave's death.

Ata said: There is no liability after death.
