What is the legal consequence if a man admits a slave is free, then purchases that slave?

Primary text

If a man acknowledges a slave is free and subsequently buys that slave, the slave is immediately manumitted. This ruling stands because the buyer's previous declaration established the property as free, and the transaction is valid for the seller as it confirms the status of the slave as property under his claim (though the ultimate effect is manumission for the buyer). For the buyer, the purchase serves as a means of redeeming and reclaiming the individual. Upon taking possession, freedom is ruled based on the prior admission. This is analogous to a situation where two witnesses testify to a triple divorce, the judge rejects their testimony, and then the witnesses provide compensation to the husband for a Khul' (repudiation for compensation); the Khul' is valid for the husband, and for the witnesses it is an act of redemption.
