Among the subjects treated in this chapter are God's call of Moses (), the Exodus of the Israelites and the crossing of the Red Sea (), the worship of the Golden Calf () and the Fall of Man (). The main theme of the chapter is about the existence of God. It addresses this theme through stories about Moses and Adam. Sura 20 displays several thematic and stylistic patterns described by Angelika Neuwirth in Jane McAuliffe's book "The Cambridge Companion to the Qur'an." These include the eschatological prophecies of the Quran, signs of God's existence, and debate. Additionally, sura 20 employs what has been termed the "ring structure" to reinforce its central theme.
