Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan from abu al-Sabbah al-Kinaniy who has said the following: “I once asked abu ‘ Abd Allah (a.s.), about the case of a woman who gets up fasting but when the day rises or it becomes evening, she experiences Hayd (menses), if she stops fasting.

He (the Imam) said, ‘Yes, she is required to stop fasting even if it is before al-Maghrib.’ I asked abu ‘Abd Allah (a.s.), about the case of a woman who becomes clean of Hayd (menses) in the beginning of the day in the month of Ramadan, does not take Ghusl (bath) and does not eat; what should she do about that day. He (the Imam) said, ‘Blood discharge has invalidated her fast.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (6/343))
