Muwatta Malik, Book 15, Hadith 50 (USC-MSA) ⓘ
Yahya related to me from Malik from Ibn Shihab from as-Sa'ib ibn Yazid that he saw Umar ibn al-Khattab beating al-Munkadir for praying after asr.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنِ السَّائِبِ بْنِ يَزِيدَ، أَنَّهُ رَأَى عُمَرَ بْنَ الْخَطَّابِ يَضْرِبُ الْمُنْكَدِرَ فِي الصَّلاَةِ بَعْدَ الْعَصْرِ .
