Mukhlad bin Khafaf narrated that I bought a slave, then benefited from him, then found a defect in him. So I filed a case about it with Umar bin Abdul Aziz (may Allah have mercy on him), and he ruled that I should return the slave and also give back the grain (profit) earned from him. Then I went to Urwah (may Allah have mercy on him), and when I told him the matter, he said: I will go to him (Umar) in the evening and inform him that Aisha (may Allah be pleased with her) told me that the Messenger of Allah (ﷺ) ruled in such a case that the income belongs to the one who is liable and responsible for bearing the loss. I quickly went to Umar bin Abdul Aziz (may Allah have mercy on him) and told him what Urwah had narrated from Aisha (may Allah be pleased with her) from the Prophet (ﷺ). So Umar (may Allah have mercy on him) said: How easy it is for me to change my decision. Allah knows that I intended nothing but the truth in this matter, but now the way of the Messenger of Allah (ﷺ) has reached me in this matter, so I revoke Umar’s decision and implement the Sunnah of the Messenger of Allah (ﷺ). Then in the evening Urwah (may Allah have mercy on him) also came to him, and he ruled for me that I should take back that income.
