The Prophet ﷺ visited me when I was sick in Mecca.I said, "I have wealth. Shall I bequeath all of it?"He replied, "No."I asked, "Then half?"He said, "No."I asked, "Then a third?"He said, "A third, and a third is plenty. To leave your heirs wealthy is better than to leave them destitute, begging from people. Whatever you spend will count as charity for you, even the morsel you raise to your wife's mouth. Perhaps Allah will raise your station, so that some people will benefit through you and others will be harmed by you."
كان النبي ﷺ يعودني وأنا مريض بمكة، فقلت: لي مال أوصي بمالي كله؟ قال: لا قلت: فالشطر؟ قال: لا قلت: فالثلث؟ قال: الثلث والثلث كثير، أن تدع ورثتك أغنياء خير من أن تدعهم عالة يتكففون الناس في أيديهم، ومهما أنفقت فهو لك صدقة حتى اللقمة ترفعها في في امرأتك، ولعل الله يرفعك، ينتفع بك ناس، ويضر بك آخرون.
Bukhari narrated it in the Book of Expenditures (5354), and Muslim in the Book of Wills (1628), both through the route of Sufyan, from Saad bin Ibrahim, from Amir bin Saad, from Saad, as mentioned above. The wording given is that of Bukhari, and Muslim did not present his own wording.The hadith is also found in Muwatta Malik in the Book of Wills (4), from Zuhri, from Amir bin Saad bin Abu Waqqas, from his father, at greater length, in which he said, "Shall I give two-thirds of my wealth in charity..." and so on.The difference lies in the question, for it seems he first asked about giving away all of it, then two-thirds, then half, then a third. All of this occurs in Sahih Muslim through the route of Humayd bin Abdul-Rahman Al-Himyari, from three of Saad's sons, each of whom reported it to him from their father.
