“I once wrote to the man (a.s.), and asked him about the case of a man who had bought camels or cows for sacrificial offering. When he slaughtered, he found a bag of dinar or diamond inside the animal. To whom this found property belong?’ He (the Imam) (a.s.), wrote back to me, ‘He must announce it before the seller and if he did not know about it, then whatever is found is what Allah has granted to him.’”
