Mukhtasar Bukhari

It was asked from Sayyiduna Abdullah bin Abi Awfa (may Allah be pleased with him) whether the Prophet (peace and blessings of Allah be upon him) made any bequest (wasiyyah)? He said: No. It was asked: Then how was bequest made obligatory or how was he commanded to make a bequest? He said: The Prophet (peace and blessings of Allah be upon him) made a bequest to act upon the Book of Allah.
