It is narrated from Hazrat Abu Yahya Al-A'raj (may Allah be pleased with him) that it was asked from the Noble Prophet (peace and blessings be upon him) that a slave was set free by his master at the time of his (the master's) death, and he (the master) had no other wealth besides him, and there is also debt upon him (the master). The Holy Prophet (peace and blessings be upon him) ordered that the slave should strive to pay off his master's debt.
