Al-Husayn ibn Said narrated that from Safwan ibn Yahya, from Ishaq ibn Ammar, who said: I said to Imam عليه السلام: “A man buys a young female slave and keeps her with him so that she may increase in value, while he intends to sell her; is there zakat upon her price?” Imam عليه السلام said: “No, not until he sells her.” I (narrator) asked: “Then if he sells her, should he give zakat on her price?” Imam عليه السلام said: “No, not until a year passes over it while it is in his hand.”
