Abayah bin Rifa'ah (may Allah have mercy on him) narrates that his grandfather (Sayyiduna Rafi', may Allah be pleased with him) died and left a slave girl who earned money. This was mentioned to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) disliked the earnings of the slave girl and said: "Perhaps she will find nothing and will then earn by means of herself."
Ibn Abi Shaybah stated it in his chain as follows: Hushaym narrated from Abu Balj, from Abayah bin Rifa'ah bin Rafi' al-Ansari.
