"I asked him about a man who bought a slave from another man, and the seller had two slaves. The seller said to the buyer, 'Take them both, then choose one of them and return the other,' and he had already received the payment. The buyer took both slaves, but one of them escaped while in his possession. Imam (as) said: 'He should return the one that is with him and reclaim half of the price he paid from the seller. Then, he may search for the escaped slave. If he finds him, he may choose either of them and return the other. But if he does not find him, then the slave that remains will be shared between them-half belonging to the seller and half to the buyer.'"
