I asked `Abdullah bin Abu `Aufa "Did the Prophet (ﷺ) make a will? ' He replied, "No." I further asked, "How comes it that the making of a will was enjoined on the people or that they were ordered to make it? " He said, "The Prophet (ﷺ) made a will concerning Allah's Book."
Sahih al-Bukhari Book 64, Hadith 476
← Previous Hadith It was mentioned in the presence of `Aisha that the Prophet (ﷺ) had appointed `Ali as successor by will. Thereupon she said, "Who said so? I saw the Prophet, while I was supporting him against my chest. He asked for a tray, and then fell on one side and expired, and I did not feel it. So how (do the people say) he appointed `Ali as his successor?"

Sahih al-Bukhari Book 64, Hadith 475 Next Hadith → Allah's Messenger (ﷺ) did not leave a Dinar or a Dirham or a male or a female slave. He left only his white mule on which he used to ride, and his weapons, and a piece of land which he gave in charity for the needy travelers.
