Imam Ja'far al-Sadiq (may Allah have mercy on him) narrates from his father (Imam Muhammad al-Baqir, may Allah have mercy on him), who narrates from Imam Zayn al-Abidin (may Allah have mercy on him), that Sayyiduna Ali (may Allah be pleased with him) said: "(The buyer) will not return (the slave-girl with a defect), rather, the amount by which the price is reduced due to the defect will be returned to him." This narration is also mursal.
