8. Ali has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthaman from al-Halabiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘The waiting period of a woman who does not experience Hayd (menses) and one who experiences Istihadah which does not become clean for three months, their waiting period is three months. Waiting period of a woman whose Hayd is straight is three Hayd-free periods.’ I then asked about the meaning of the words of Allah, most Majestic, most Glorious, ‘. . . if you have doubt.’ He (the Imam) said, ‘This ‘doubt’ is about what is more than one month, thus, she counts her waiting period for three months and ignores Hayd. Whatever of Hayd is in a month which does not increase in Hayd her waiting period is three cycles of Hayd.”’

9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Ali ibn Faddal from ibn Bukayr from Zurarah who has said the following: “One of the two Imam, (abu Ja‘far or abu ‘Abd Allah), ‘Alayhim al-Salam, has stated this Hadith. ‘Of the two issues whichever comes first, it marks the end of her waiting period: one is passing of three months in which she does not see Hayd (menses), thus her waiting period ends. If three Hayd-free periods pass this also marks the end of her waiting period.’”

10. Muhammad has narrated from Ahmad from Ali ibn al-Hakam from Musa ibn Bakr from Zurarah who has said the following: “He (the Imam) (a.s.), has said, ‘If she waits and does not find the Hayd (menses)-free period except three months then if her Hayd (menses) is not straight. If she experiences Hayd in a month several times such woman’s waiting period is like the waiting period of one who experiences Istihadah, whose ‘Iddah (waiting period) is three months. If she experiences Hayd straightly, thus, in every month is one Hayd and between two Hayd (menses) one month of time it is the Hayd-free period.’”

11. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Yazid ibn Ishaq Sha‘ir from Harun ibn Hamzah who has said the following: “About the case of a woman who is divorced and is old but experiences Hayd (menses) once then her Hayd stops, abu ‘Abd Allah (a.s.), has said, ‘She must count her waiting period for one Hayd and two months in future because she has reached menopause.’”
