Musannaf Ibn Abi Shaybah 33524 — The apostate from Islam: who inherits

Waki' said: I heard Sufyan say: If an apostate goes to the abode of war (Dar al-Harb) and then returns before his inheritance is divided, or before the ruler frees the mothers of his children (umm walad) and his mudabbarah (the slave woman to be freed at his death), then he has the most right to them.
