‘A'isha reported the Prophet as saying, “The pleasantest things you enjoy come from what you earn, and your children come from what you earn”*. The version of Aba Dawud and Darimi has, “The pleasantest things a man enjoys come from what he earns and his child comes from what he earns.” Tirmidhi, Nasa’i and Ibn Majah transmitted it. *Or “are a part of your earnings.” The phrase expresses two ideas:the children are the result of marriage, and parents who are in need may receive support from their children.
