Abu Hurairah (May Allah be pleased with him) reported:
The Prophet ﷺ said, "No food is better to man than that which he earns through his manual work. Dawud ﷺ, the Prophet of Allah, ate only out of his earnings from his manual work."

[Al-Bukhari].

وعن المقدام بن معد يكرب رضي الله عنه، عن النبي ﷺ قال: " ما أكل أحد طعاماً قط خيراً من أن يأكل من عمل يده، وإن نبى الله دواد ﷺ كان يأكل من عمل يده". ((رواه البخاري)).
