Sahih Bukhari

Narrated Sa`d:I fell sick and the Prophet (ﷺ) paid me a visit. I said to him, ""O Allah's Messenger (ﷺ)! I invoke Allah that He may not let me expire in the land whence I migrated (i.e. Mecca)."" He said, ""May Allah give you health and let the people benefit by you."" I said, ""I want to will my property, and I have only one daughter and I want to will half of my property (to be given in charity)."" He said,"" Half is too much."" I said, ""Then I will one third."" He said, ""One-third, yet even one-third is too much."" (The narrator added, ""So the people started to will one third of their property and that was Permitted for them)
