Sayyiduna Amr bin al-As (may Allah be pleased with him) narrates that do not make the Sunnah of our Noble Prophet (peace and blessings of Allah be upon him) doubtful for us. If an umm walad (a slave woman who has borne a child to her master) loses her husband, then her waiting period (‘iddah) is the same as that of a (free) woman whose husband has died.
