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 ﷺ forbade us to fast, and told us to break the fast on them." Malik said, "These days are the days of tashriq."  

أَنَّهُ أَخْبَرَهُ أَنَّهُ دَخَلَ عَلَى أَبِيهِ عَمْرِو بْنِ الْعَاصِ فَوَجَدَهُ يَأْكُلُ قَالَ فَدَعَانِي قَالَ فَقُلْتُ لَهُ إِنِّي صَائِمٌ فَقَالَ هَذِهِ الأَيَّامُ الَّتِي نَهَانَا رَسُولُ اللَّهِ ﷺ عَنْ صِيَامِهِنَّ وَأَمَرَنَا بِفِطْرِهِنَّ
