Is the son of a mawla a mawla? Are they free? And does the one who frees a slave inherit from his freed mawla?

The questioner : But may Allah reward you, you did not expose this. In the mosque, regarding his being a mawla, and the Prophet (peace and blessings be upon him) freed his father, how can he be a mawla?

The Shaykh : Because the son of a mawla is a mawla.

The questioner : But his father made a mistake.

The Shaykh : I say the son of a mawla is a mawla; this is what all the scholars said. It is forbidden, even if he is free after manumission, but they hold that the descendants of a mawla are among the mawali. So Usamah is a mawla, and therefore in the chapter of inheritance, he inherits by the bond of loyalty, meaning the one who freed him inherits from him by the bond of loyalty. If the son of the freed man dies and has no close relative, his freed father inherits from him because he is his mawla.
