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 .

Yahya added that Malik commented, "It is said that everything has a short measure and a full measure
