Narated By Rafi' ibn Rifa'ah : Tariq ibn AbdurRahman al-Qarashi said: Rafi' ibn Rifa'ah came to a meeting of the Ansar and said: The Prophet of Allah (pbuh) forbade us (from some things) today, and he mentioned some things. He forbade the earning of a slave-girl except what she earned with her hand. He indicated (some things) with his fingers such as baking, spinning, and ginning.
