Hadith 1
The Book of Financial Transactions
It was narrated that 'Aishah said:
"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 اللَّهِ بْنُ سَعِيدٍ أَبُو قُدَامَةَ السَّرَخْسِيُّ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ سُفْيَانَ، عَنْ مَنْصُورٍ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ، عَنْ عَمَّتِهِ، عَنْ عَائِشَةَ، قَالَتْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
إِنَّ أَطْيَبَ مَا أَكَلَ الرَّجُلُ مِنْ كَسْبِهِ وَإِنَّ وَلَدَ الرَّجُلِ مِنْ كَسْبِهِ
