Musnad Ahmad 33:271

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, and Ibn Numayr [narrated] from Al-A'mash, from Abu Sufyan, from Jabir, who said: I heard the Prophet, peace and blessings of Allah be upon him, say three days before his death: "Let none of you die except while he is having good expectations of Allah."
