Musnad Ahmad Hadith 3602

The Messenger of Allah (ﷺ) said: "Who among you likes his heir’s wealth more than his own wealth?” They said: O Messenger of Allah, there is no one among us for whom his own wealth is not dearer to him than his heir's wealth. He said: “You should know that there is no one among you for whom his heir's wealth is not dearer than his own wealth. You will have nothing of your wealth except what you send ahead, and your heir's wealth is what you leave behind.” And the Messenger of Allah (ﷺ) said: “Who do you consider to be a strong wrestler among you?" They said: The one who cannot be thrown to the ground by other men. He said: “No, the strong man is the one who can control himself at the time of anger." And The Messenger of Allah (ﷺ) said: "Who do you consider to be childless among you?" We said: The one who has no children. He said: “No, the childless one is the one who has not sent any of his children ahead of him (i.e., none of his children died before him)."
