A slave's wealth when he is sold: Abu Hanifah said if the slave's wealth is more than the price, that is not allowed

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The 'uhdah (option) on a slave is three days."

Al-Hasan says that the Prophet (peace and blessings be upon him) said: "There is no 'uhdah (option of return) beyond four days."

Muhammad bin Yahya bin Habban says: Sayyiduna Ibn al-Zubayr (may Allah be pleased with them both) stated the 'uhdah (for returning) a slave to be three days, because the Prophet (peace and blessings be upon him) had said to Sayyiduna Munqidh bin Amr (may Allah be pleased with him): "(When you buy, then) say: 'There is no deception.' When you sell something, you will have the option for three days."

Abdullah bin Abi Bakr narrates: I heard Aban bin Uthman and Hisham bin Isma'il teaching about the 'uhdah on a slave: for fever and (an ailment of) the belly there is an option of three days, and for insanity and leprosy an option of one year. It is mentioned that the view of (Imam) Abu Hanifah is: When the two contracting parties have separated, they no longer have the right to return the sold item unless there is a defect.
