Ibn Abbas reported: Umar ibn al-Khattab, may Allah be pleased with him, passed by some people one day who were eating while their servants were standing. Umar said, “Why do I not see your servants eating with you? Do you not desire them?” A man said, “No, by Allah, O leader of the faithful. Rather, we have preference over them.” Umar became very angry, then he said, “What is the matter with people who prefer themselves over their servants? Allah Almighty will deal with them and it is done!” Then Umar said to the servants, “Sit down and eat.” The servants sat to eat and the leader of the faithful did not eat.

عن ابن عباس قال مر عمر بن الخطاب رضي الله عنه يوماً فرأى القوم يأكلون وقام الخُدَّام فقال عمرُ مالي لا أَرى خُدَّامَكم يأكلون معكم أترغبون عنهم فقال لا واللهِ يا أميرَ المؤمنين ولكنَّا نستأثرُ عليهم فغضب غضبًا شديدًا ثم قال ما لقومٍ يستأثرون على خُدَّامهم فَعَلَ الله تعالى بهم وفَعَلَ ثم قال للخُدَّام اجلِسوا فكُلُوا فقَعَدَ الخدَّام يأكلون ولم يأكلْ أميرُ المؤمنينَ
