The noun nafs has important instances in the Quran such as the following: "O you who have believed, upon you is [responsibility for] yourselves..."[1] The major theme of the word nafs as used in the Quran is to instill a sense of individual responsibility through a strong emphasis on the choices made by the individual (as in 5:105), while at the same time reminding humanity of its common origins (verse 4:1).
