Musnad Abu Ya'la al-Mawsili 109:291

Narrated to us Ibn Numayr, narrated to us my father, narrated to us al-A'mash, from Abu Sufyan, from Jabir, who said: I heard the Messenger of Allah (may Allah bless him and grant him peace) saying three days before his death: "Let not any one of you die except while he thinks well of Allah."
