Tariq bin Abd al-Rahman al-Qurashi said: Rifa'ah bin Rafi' (may Allah be pleased with him) came to the gathering of the Ansar and said: Today the Messenger of Allah (peace and blessings be upon him) forbade us certain things; he forbade us "the earnings of a slave-woman except what she earned with her own hand", and he gestured with his finger, like spinning, baking bread and embroidery.
