Ibn ‘Abbas reported the Prophet as saying, “When a slave who has made an agreement to purchase his freedom gets blood-money or an inheritance, he can inherit in accordance with the extent to which he has been emancipated.”
In a version by Tirmidhi he said, “Blood wit is paid for a slave who has made an agreement to purchase his freedom at the rate paid for a freeman so far as he has paid the purchase money, and at the rate paid for a slave so far as the remainder is concerned,” but he declared it to be weak.
Abu Dawud and Tirmidhi transmitted it.
