5. A number of our people have narrated from Sahl ibn Ziyad from al-Hassan ibn Mahbub from Ali ibn Ri’ab from Sama‘ah ibn Mehran who has said the following: “I once asked abu ‘Abd Allah , about the case of a woman who experiences Istihadah. He (the Imam) said, ‘She is required to fast in the month of Ramadan except for the days during which she used to experience Hayd (menses) and thereafter complete its Qada’ (compensatory fast).”’
