This section contains another of the patterns discussed by Neuwirth, the signs of God's existence. It references the ruins of old cities as signs that God exists and can easily destroy people. Also, this section instructs believers to pray, and not to long for others' possessions. Verse 131 is the second verse of the sura that is mentioned in Asbab al-Nuzul. Wahidi says that this was sent down because Muhammad once desired food to entertain a guest, but could not afford it. The Jewish man selling the food refused to sell it without a security, and Muhammad was furious with this. To appease his prophet, God sent down this verse.
