Musannaf Ibn Abi Shaybah

Umar narrates the statement of Hazrat Sha’bi that if the son of a woman who has performed li’an dies and leaves behind his maternal uncle and maternal aunt, all his wealth will be given to the maternal uncle.

Hamzah narrates that Hazrat Ibn Abi Layla used to say that the maternal uncle is entitled to two-thirds of the wealth and the maternal aunt to one-third of the wealth.
