BEST KIND OF FOOD H 544 "No one eats better food than that procured through the labor of his hands. David, a Prophet of Allah, ate only from the earnings of his labor." R 544 Bukhari - Miqdad, the son of Ma'dikarib who related that the Prophet, praise and peace be upon him, said this.
542- وعن المقدام بنِ مَعْدِ يكرِبَ رضي الله عنه ، عن النبي صلى الله عليه وآله وسلم ، قَالَ : "مَا أكَلَ أَحَدٌ طَعَاماً قَطُّ خَيْراً مِنْ أنْ يَأكُلَ مِنْ عَمَلِ يَدِه ، وَإنَّ نَبيَّ الله دَاوُدَ صلى الله عليه وآله وسلم كَانَ يَأكُلُ مِنْ عَمَلِ يَدِهِ" رواه البخاري .
