It is narrated from Rafi' bin Rifa'ah, he says: The Noble Prophet (peace and blessings be upon him) forbade us from the earnings of the cupper, and instructed us that we should feed such earnings to irrigation camels and the like. Also, he (peace and blessings be upon him) forbade us from the earnings of slave-girls, except for what they earn by working with their own hands (that is permissible). Then he (peace and blessings be upon him) gestured with his hand towards making bread, spinning cotton or wool, or carding them.
