Musannaf Ibn Abi Shaybah

Waki‘ narrated from Sufyan regarding that Magian who marries his own daughter, then has two daughters from her, and after the father's death, if one of them dies. He said: Her full sister gets half of the wealth, and her paternal sister, who is her mother, gets one-sixth of the wealth, to complete two-thirds of the wealth. He deprived himself because of his own self.
