Aisha bint Abi Bakr · Shares of Inheritance (Kitab Al-Fara'id)

I heard the Messenger of Allah (ﷺ) say: I am the heirs of Him who has none, freeing him from his liabilities, and inheriting what he possesses. A maternal uncle is the heir of Him who has none, freeing him from his liabilities, and inheriting his property.

The Prophet (ﷺ) said: An estate which was divided in pre-Islamic period may follow the division in force then, but any estate in Islamic times must follow the division laid down by Islam.

'Aishah, mother of believers (ra), intended to buy a slave-girl to set her free. Her people said: We shall sell her to you on one condition that we shall inherit from her. 'Aishah mentioned it to the Messenger of Allah (ﷺ). He said: That should not prevent you, for the right of inheritance belongs to the one who has set a person free.
