سنن النسائي

'Amir bin Sa'd (narrated) from his father that he fell sick in Makkah and the Messenger of Allah (ﷺ) came to him. When Sa'd saw him, he wept and said: "O Messenger of Allah, am I to die in the land from which I emigrated?" He said: "No, if Allah wills." He said: "O Messenger of Allah, shall I bequeath all of my wealth in the cause of Allah?" He said: "No." He said: "Two-thirds?" He said: "No." He said: "Half of it?" He said: "No." He said: "One-third of it?" The Messenger of Allah (ﷺ) said: "One-third, and one-third is a lot. If you leave your sons independent of means that is better than if you leave them poor, holding out their hands to people."
