It was narrated from Miqdam bin Ma'dikarib (Ar- Zubaidi) that the Messenger of Allah ﷺ said:
"No man earns anything better than that which he earns with his own hands, and what a man spends on himself, his wife, his child and his servant, then it is charity."

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، عَنْ بَحِيرِ بْنِ سَعْدٍ، عَنْ خَالِدِ بْنِ مَعْدَانَ، عَنِ الْمِقْدَامِ بْنِ مَعْدِيكَرِبَ الزُّبَيْدِيِّ، عَنْ رَسُولِ اللَّهِ ﷺ قَالَ " مَا كَسَبَ الرَّجُلُ كَسْبًا أَطْيَبَ مِنْ عَمَلِ يَدِهِ وَمَا أَنْفَقَ الرَّجُلُ عَلَى نَفْسِهِ وَأَهْلِهِ وَوَلَدِهِ وَخَادِمِهِ فَهُوَ صَدَقَةٌ " .
