Musnad Abu Ya'la al-Mawsili 109:279

Ibn Numayr narrated to us, Muhammad ibn ‘Ubayd narrated to us, al-A‘mash narrated to us, from Abu Sufyan, from Jabir, who said: A man came to the Prophet, may Allah bless him and grant him peace, and said: "What are the two things that make [something] necessary?" He said: "Whoever dies not associating anything with Allah enters Paradise, and whoever dies associating anything with Allah enters the Fire."
