Musa says that his grandmother passed away in the presence of Hazrat Abu Burdah, may Allah have mercy on him. Hazrat Abu Burdah kept some of her slave girls for himself. I said to him, "Ibn Aun narrated to you from Muhammad that if a person intends to take a slave girl belonging to a small child, he should appraise her value for him and appoint a witness to her price for him?" He replied, "Yes, I have heard this."
