9. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Ja’far who has said the following: “I once wrote to the man , 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) , 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.’”
