Sahih al-Bukhari 6120

'Amir ibn Sa'd ibn Abi Waqqas related that his father said, "I became very ill in Makka and thought I was going to die. The Prophet, may Allah bless him and grant him peace, came to visit me and I said, 'Messenger of Allah, I have a lot of property and my only heir is one daughter. Should I will away two-thirds of my property and leave a third?' 'No,' he answered. I said, 'A half?' 'No,' he answered. I said, 'A third?' He said, 'A third is a lot. It is better to leave your heirs wealthy than to make them beg from people with their hands. Whatever you spend on maintenance is sadaqa, even the morsel you put in your wife's mouth.' I said, 'Messenger of Allah, will I be left behind my hijra?' He said, 'You will not be left behind, for any virtuous actions you do will raise you in degree and elevation. If you are left behind me, perhaps some people will benefit from you and others harmed by you, but poor Sa'd ibn Khawla!' The Messenger of Allah, may Allah bless him and grant him peace, grieved over his dying in Makka." Sufyan said, "Sa'd ibn Khawla was a man from the Banu 'Amir ibn Lu'ayy."
