1. This is the introduction to this Surah, in which its aim and object has been enunciated in a few words. Allah has addressed the Prophet (peace be upon him) to this effect: O Prophet, most of your people are rejecting the teachings of the Quran for one reason or the other, but the fact is that what We are sending down to you is the truth whether people believe it or not.
After this brief introduction, the discourse deals with the main subject of the Surah which consists of three basic things. First, the entire universe belongs to Allah alone, and none besides Him has any right to service and worship. Second, there is another life after this life in which you shall have to render an account of all your actions. Third, I am a Messenger of Allah: whatever I am presenting before you is not from myself but from Allah. As the people were rejecting these three things, these have been reiterated over and over again in various forms to remove doubts and objections from the minds of the disbelievers.
