Muwatta Malik · #22
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، انْصَرَفَ مِنْ صَلاَةِ الْعَصْرِ فَلَقِيَ رَجُلاً لَمْ يَشْهَدِ الْعَصْرَ فَقَالَ عُمَرُ مَا حَبَسَكَ عَنْ صَلاَةِ الْعَصْرِ فَذَكَرَ لَهُ الرَّجُلُ عُذْرًا فَقَالَ عُمَرُ طَفَّفْتَ . قَالَ يَحْيَى قَالَ مَالِكٌ وَيُقَالُ لِكُلِّ شَىْءٍ وَفَاءٌ وَتَطْفِيفٌ .
