Sa‘d b. Abu Waqqas said

During an illness which brought me near to death in the year of the Conquest Allah's Messenger ﷺ came to visit me and I said, “ Messenger of Allah , I have a large amount of property and my daughter is my only heir. Shall I will away all my property ?” He replied, ‘No” I suggested two-thirds, but he objected, then a half, but he still objected. When I suggested a third he replied, “You may will away a third, but that is a lot*. To leave your heirs rich is better than to leave them poor and begging from people. You will not spend anything, seeking thereby to please Allah, without being rewarded for it, even the mouthful you give your wife.” *While this tradition tells that the Prophet (ﷺ) gave permission for a man to will away a third of his estate to some person or purpose other than the heirs, it indicates that be thought it would be better not to will away so much. (Bukhari and Muslim.)
