Narrated Al-Miqdam:
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى ، أَخْبَرَنَا عِيسَى ، عَنْ ثَوْرٍ ، عَنْ خَالِدِ بْنِ مَعْدَانَ ، عَنِ الْمِقْدَامِ ـ رضى الله عنه ـ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " مَا أَكَلَ أَحَدٌ طَعَامًا قَطُّ خَيْرًا مِنْ أَنْ يَأْكُلَ مِنْ عَمَلِ يَدِهِ، وَإِنَّ نَبِيَّ اللَّهِ دَاوُدَ ـ عَلَيْهِ السَّلاَمُ ـ كَانَ يَأْكُلُ مِنْ عَمَلِ يَدِهِ " .
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."
