Musannaf Ibn Abi Shaybah 20423 — A miscarried fetus: does the waiting

Al-Hasan (may Allah have mercy on him) said: When a woman gives birth to the child in the state of a clot of blood or a lump of flesh, after it had become known that she was pregnant, then the ghurrah (compensation) is due for it, and her waiting period is completed by it, and if she is an umm walad (a slave-woman who bore her master's child), she becomes free.
