The purpose of this chapter is a general call in the form of a warning. It begins by mentioning the signs of God’s oneness, before the promulgation of a divine code (shariah) for the Prophet. Then it emphasizes the importance of following this code for him and others because ahead of them lies a day on which they will be recompensed for their righteous deeds – such as having faith and following the Prophet’s teachings – and they will only hurt themselves with evil deeds if they turn away from the religion. Finally, it mentions what will become of both groups on that day, namely the Day of Resurrection.
Throughout its topics, there is a severe warning and threat of punishment for those who arrogantly defy God’s signs, and those who take their own desires as gods, and whom God misguides upon knowledge.
One of the most fascinating subjects discussed in this chapter is how deeds are written down and recorded.
Based on the tone and content of its verses, this is a Meccan chapter, although some commentators made an exception for the verse Say to the faithful… (45:14). However, there is nothing to attest to their opinion.
