Narrated Aisha, Ummul Mu'minin:

The aunt of Umarah ibn Umayr asked Aisha: I have an orphan in my guardianship. May I enjoy from his property? She said: The Messenger of Allah ﷺ said: The pleasantest things a man enjoys come from what he earns, and his child comes from what he earns.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنْ عَمَّتِهِ، أَنَّهَا سَأَلَتْ عَائِشَةَ رضى الله عنها فِي حِجْرِي يَتِيمٌ أَفَآكُلُ مِنْ مَالِهِ فَقَالَتْ قَالَ رَسُولُ اللَّهِ ﷺ
" إِنَّ مِنْ أَطْيَبِ مَا أَكَلَ الرَّجُلُ مِنْ كَسْبِهِ وَوَلَدُهُ مِنْ كَسْبِهِ " .
