Hashim narrated from Ibn Abi Layla and Hajjaj, from Ikrimah bin Khalid Makhzumi, that a woman was brought before Sayyiduna Umar bin Khattab (may Allah be pleased with him) who testified about a man and his wife that she had breastfed both of them. So Sayyiduna Umar bin Khattab (may Allah be pleased with him) said: "No, not unless two men or one man and two women testify."
