Al-Adab Al-Mufrad #501

It is narrated by Sayyidah Ayeshah daughter of Sad that her father Sad bin Abu Waqqas said: I was seriously ill at Makkah and the Prophet visited me. I said to him "Messenger of Allah, I shall leave behind me a good fortune and I have only a daughter (as my heir). Shall I bequeath two-thirds of my property to be spent in charity and leave one-third (for the heir)?" He said, "No!" Then I asked, "Shall I bequeath half and leave her half?" He again said, "No". Then I asked, "Shall I Bequeath one-third and leave two- third (for her)?" the Prophet said,"(You may bequeath) one-third, but even one-third is much". He then placed his hand on my forehead and passed it over my face and stomach and made this supplication. "O Allah, cure sad and completed his emigration." Ever since I have not ceased to sense the pleasant cool of his hand on my liver."
