What is the amount that must be paid to the woman for her share in a cow gifted to her by her father, considering that she was born about ten years before its sale, and that her share in the price of the original cow is 3500 pounds? And does she have a right to the offspring of the cow?

It is permissible to give a cow to someone who will raise and care for it in exchange for an agreed-upon share, such as half, whereby both parties become partners in its growth and offspring. The partnership between the questioner and her father-in-law is considered valid, and a duration for the partnership should have been specified. If the cow was sold, the questioner is entitled to half of the price. However, due to 10 years having passed since the sale and the decrease in currency value, if the questioner had demanded her right and her father-in-law procrastinated, he must now give her the value of half of a cow similar to the first one. But if the questioner did not demand her right, or her father-in-law was in hardship, the decrease in currency value should be divided between them by mutual consent. As for the offspring of the cow, the questioner is entitled to half of them because she owns half of the mother, and the growth belongs to both parties according to each one's ownership.
