Encouraging Livelihood by (working with) Hands and Abstaining from Begging
وَعَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: كان دَاوُد عَلَيْهِ السلام لاَ يَأْكُلُ إِلاَّ مِنْ عَمَلِ يَدِهِ . ((رَوَاهُ الْبُخَارِيّ)).
Abu Hurairah (May Allah be pleased with him) reported: The Prophet (ﷺ) said, "(Prophet) Dawud (ﷺ) ate only out of that which he earned through his manual work." [Al-Bukhari].
