Ibn Shihab (may Allah have mercy on him) says: When the first fitnah (civil strife) flared up, it reached many of the Companions who had been at Badr (may Allah be pleased with them) as well. And it reached us that they held that the matters of the fitnah were to be disregarded: no retaliation (qisas) was imposed on anyone who killed in it on the basis of an interpretation of the Qur'an; there was no hadd punishment concerning a woman taken captive (in it) — no hadd was considered due upon her, nor was li'an conducted between her and her husband; they held that whoever accused her (of adultery) was to be flogged the hadd punishment; and they held that she was to be returned to her first husband after completing her waiting period ('iddah) from the second husband, and that her first husband would inherit from her.
