"The Messenger of Allah said: "The best (most Pure) food that a man eats is that which he has earned himself, and a man's child (and his child's wealth) is part of his earnings" (Sahih )

أَخْبَرَنَا عُبَيْدُ اللهِ بْنُ سَعِيدٍ قَالَ حَدَّثَنَا يَحْيَى عَنْ سُفْيَانَ عَنْ مَنْصُورٍ عَنْ إِبْرَاهِيمَ عَنْ عُمَارَةَ بْنِ عُمَيْرٍ عَنْ عَمَّتِهِ عَنْ عَائِشَةَ قَالَتْ

قَالَ رَسُولُ اللهِ ﷺ «إِنَّ أَطْيَبَ مَا أَكَلَ الرَّجُلُ مِنْ كَسْبِهِ وَإِنَّ وَلَدَ الرَّجُلِ مِنْ كَسْبِهِ»
