Narated By Abdullah ibn Amr ibn al-'As : A man came to the Prophet (pbuh) and said: Apostle of Allah, I have property and children, and my father finishes my property. He replied; You and your property belong to your father; your children come from the pleasantest of what you earn; so enjoy from the earning of your children.
