Umar bin Hafs bin Ghyath عمر بن حفص بن غياث · Wages (Kitab Al-Ijarah)

A man bought a slave, and he remained with him as long as Allah wished him to remain. He then found defect in him. He brought his dispute with him to the Prophet (ﷺ) and he returned him to him. The man said: Messenger of Allah, my slave earned some wages. The Messenger of Allah (ﷺ) then said: Profit follows responsibility. Abu Dawud said: This chain of narrators (of this version) is not reliable.
