The Prophet ﷺ said, "Nobody has ever eaten a better meal than that which one has earned by working with one's own hands. The Prophet ﷺ of Allah, David used to eat from the earnings of his manual labor."

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ مَا أَكَلَ أَحَدٌ طَعَامًا قَطُّ خَيْرًا مِنْ أَنْ يَأْكُلَ مِنْ عَمَلِ يَدِهِ وَإِنَّ نَبِيَّ اللَّهِ دَاوُدَ عَلَيْهِ السَّلاَمُ كَانَ يَأْكُلُ مِنْ عَمَلِ يَدِهِ
