Muwatta Malik Book 20, Hadith 139 Next Hadith → Yahya related to me from Malik from Yazid ibn Abdullah ibn al- Hadi from Abu Murra, the mawla of Umm Hani, the sister of Aqil ibn Abi Talib, that Abdullah ibn Amr ibn al-As told him that he had visited his father Amr ibn al-As and found him eating. His father had invited him to eat, and when he replied that he was fasting, his father said, "These are the days on which the Messenger of Allah, may Allah bless him and grant him peace, forbade us to fast, and told us to break the fast on them."

Malik said, "These days are the days of tashriq."
