Al-Miqdam b. Ma'dikarib reported God's Messenger as saying, “No one has ever eaten better food than what he eats as a result of the labour of his hands. God’s prophet David used to eat from what he had worked for with his hands.” Bukhari transmitted it.
عَن الْمِقْدَاد بْنِ مَعْدِي كَرِبَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا أَكَلَ أَحَدٌ طَعَامًا قَطُّ خَيْرًا مِنْ أَنْ يَأْكُلَ مِنْ عَمَلِ يَدَيْهِ وَإِنَّ نَبِيَّ اللَّهِ دَاوُدَ عَلَيْهِ السَّلَامُ كَانَ يَأْكُلُ مِنْ عمل يَدَيْهِ» . رَوَاهُ البُخَارِيّ
