question #1 Sahih al-Bukhari 2141, Book 34, Hadith 93 : What is the Islamic ruling on manumitting a slave after the owner’s death?

A man decided that a slave of his would be manumitted after his death and later on he was in need of
money, so the Prophet (ﷺ) took the slave and said, “Who will buy this slave from me?” Nu’aim bin
`Abdullah bought him for such and such price and the Prophet (ﷺ) gave him the slave.
