Musannaf Ibn Abi Shaybah 17979 — A woman whose husband dies

Sa'id bin al-Musayyib (may Allah have mercy on him) said: Sayyiduna Umar (may Allah be pleased with him) consulted Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) and Sayyiduna Zayd bin Thabit (may Allah be pleased with him) about this. Sayyiduna Zayd (may Allah be pleased with him) said: "As soon as she gives birth, the woman's waiting period is complete." Sayyiduna Ali (may Allah be pleased with him) said: "Her waiting period is four months and ten days." Sayyiduna Zayd said: "If the woman has reached an age at which pregnancy and childbirth are not conceivable, what will her waiting period be?" Sayyiduna Ali (may Allah be pleased with him) said: "The longer of the two periods will be the period of her waiting period." Sayyiduna Umar (may Allah be pleased with him) said: "If the body of the pregnant woman's husband has not yet been lowered into the grave and she gives birth, that woman's waiting period is complete."
