Musnad Ahmad 33:1093

An-Nadr ibn Isma'il Abu al-Mughirah narrated to us, Ibn Abi Layla narrated to us, from Abu al-Zubayr, from Jabir, who said: A man came to the Prophet, peace and blessings of Allah be upon him, and said: "O Messenger of Allah, which prayer is best?" He said: "The length of the standing (al-qunut)." He said: "O Messenger of Allah, and which jihad is best?" He said: "He whose horse is hamstrung and his blood is spilled." He said: "O Messenger of Allah, which migration is best?" He said: "He who abandons what Allah dislikes." He said: "O Messenger of Allah, which of the Muslims is best?" He said: "He from whose tongue and hand the Muslims are safe." He said: "O Messenger of Allah, what are the two things that make [Paradise or Hell] inevitable?" He said: "Whoever dies not associating anything with Allah enters Paradise, and whoever dies associating anything with Allah enters the Fire."
