Muhammad bin Sa’d (Ibn Abi Waqqas) narrated from his father that the Messenger of Allah (peace be upon him) came to him in Makkah, and he had only one daughter. Sayyiduna Sa’d (bin Abi Waqqas, may Allah be pleased with him) said: I said to you, O Messenger of Allah, I have only one daughter, shall I bequeath all my wealth (for charitable purposes)? The Prophet (peace be upon him) said: “No.” I said: Then shall I bequeath half of my wealth? The Prophet (peace be upon him) said: “No.” He said: Then shall I bequeath a third? Sayyiduna Sa’d (may Allah be pleased with him) said: The Messenger of Allah (peace be upon him) said: “Yes, a third, though a third is still much.”
Hadith Referenceسنن دارمي / من كتاب الوصايا / 3227
It has been mentioned previously that if the wealth is abundant, it is recommended (mustahabb) to make a bequest (wasiyyah) for spending it on good deeds.
How admirable are the teachings of Islam! We have not been required to spend all our wealth in the path of Allah or to make a bequest to spend all of it; rather, this virtuous act has been limited. The Prophet of Islam sallallahu alayhi wa sallam permitted spending up to one third of the wealth and gave such advice—worthy of being written in golden letters—that if you leave your children wealthy, it is better than leaving them destitute and having them go around asking from people.
Subhan Allah al-Azeem! What noble Prophetic teachings these are.
