Amr bin Kharija · The Book of Wills

"O Messenger of Allah, shall I bequeath two-thirds of my wealth?" He said: "No." He said: "Shall I bequeath half?" He said: "No." He said: "Shall I bequeath one-third?" He said: "Yes, one-third, and one-third is much or large. If you leave your heirs independent of means that is better than if you leave them poor, holding out their hands."

"I do not have any children apart from one daughter. Shall I bequeath all my wealth?" The Prophet said: "No." He said: "Shall I bequeath half of it?" The Prophet said: "No." He said: "Shall I bequeath one-third of it?" He said: "One-third, and one-third is much or large."
