It is narrated from Hazrat Hakam (may Allah have mercy on him) that if a person buys a slave-girl and the seller says, "I will not hand her over to you until she menstruates," and she is entrusted to a just and trustworthy person and then she dies, Hazrat Hakam (may Allah have mercy on him) said: "She has perished from the seller's property." (The loss will be counted against the seller.)
