Sahih Adab al-Mufrad

It is narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Who among you is there who loves the wealth of his heir more than his own wealth?” The people said: O Messenger of Allah! There is none among us but that he loves his own wealth more than the wealth of his heir. Upon this, the Messenger of Allah (peace and blessings of Allah be upon him) said: “Know that there is none among you but that he loves the wealth of his heir more than his own wealth. Your wealth is only that which you have spent and sent forward, and the wealth of your heir is that which you have accumulated and left behind.”
