Sahih al-Bukhari 2744

Muhammad ibn ʿAbd al-Rahim narrated to us; Zakariyya ibn ʿAdi narrated to us; Marwan narrated to us, from Hashim ibn Hashim, from ʿAmir ibn Saʿd, from his father (may Allah be pleased with him), who said: I fell ill, and the Prophet visited me. I said, “Messenger of Allah, pray that Allah does not turn me back on my heels.” He said, “Perhaps Allah will raise you and benefit people through you.” I said, “I want to make a bequest, and I have only one daughter. May I bequeath half?” He said, “Half is much.” I asked, “Then a third?” He said, “A third—and a third is much,” or “great.” The narrator said: People thereafter made bequests of a third, and that was permitted to them.
