Muwatta Malik, Book 49, Hadith 1703 (In-Book)

Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that Anas ibn Malik said, "I saw Umar ibn al-Khattab when he was amir al-muminin being given a sa of dates, and he ate all of them, even the inferior ones."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ قَالَ رَأَيْتُ عُمَرَ بْنَ الْخَطَّابِ - وَهُوَ يَوْمَئِذٍ أَمِيرُ الْمُؤْمِنِينَ - يُطْرَحُ لَهُ صَاعٌ مِنْ تَمْرٍ فَيَأْكُلُهُ حَتَّى يَأْكُلَ حَشَفَهَا ‏.‏
