وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَانَ يَذْهَبُ إِلَى الْعَوَالِي كُلَّ يَوْمِ سَبْتٍ فَإِذَا وَجَدَ عَبْدًا فِي عَمَلٍ لاَ يُطِيقُهُ وَضَعَ عَنْهُ مِنْهُ .
Malik related to me that he heard that Umar ibn al-Khattab went to the villages every Saturday. If he found a slave doing work which he was not capable of doing, he lightened it for him.
