Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: A woman apostatized from Islam, so the Prophet (peace and blessings be upon him) ordered: "Present Islam to her; if she accepts Islam, then fine, otherwise she should be killed." Islam was presented to that woman, but she refused to accept Islam, so she was killed.
