Waiting Period of a Woman whose Hayd (menses) is Confused

7. Ali ibn Ibrahim has narrated from his father from ibn abu Nasr, from Dawud ibn al-Husayn, from abu al-‘Abbas who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about the case of a man who divorces his wife after childbirth and her becoming clean and she is a woman who does not experience Hayd (menses) as long as she breastfeeds and about how much is her waiting period. He (the Imam) said, ‘It is three months.’”
