Saeed bin Abdul Aziz narrates: Sayyiduna Abu Bakr (may Allah be pleased with him) had a woman named Umm Qirfa Fazariyyah killed as a punishment for apostasy, by way of mutilation; he had her two feet tied to two horses and had her torn into two pieces. Sayyidah Umm Waraqah Ansariyyah, whom the Noble Prophet (peace and blessings be upon him) had named "the martyr," was killed during the caliphate of Sayyiduna Umar (may Allah be pleased with him) by her male and female slaves, so Sayyiduna Umar (may Allah be pleased with him) had both of them crucified and killed.
