Ahmad bin Mansur al-Ramadi said: I said to Ali bin al-Madini: O Abu al-Hasan, do you know (the hadith) from Yahya bin Sa'id from Amrah from Sayyidah Aishah (may Allah be pleased with her) that she said: "Hafsah (may Allah be pleased with her) and I began the day fasting"? He said to me: Who narrated this? I said: Ibn Wahb from Jarir bin Hazim from Yahya bin Sa'id. He laughed and said: Someone like you says something like this? Hammad bin Zayd narrated to us from Yahya bin Sa'id from al-Zuhri that Aishah and Hafsah began the day fasting.
