Say, [O Muḥammad], "O mankind, indeed I am the Messenger of Allāh to you all, [from Him] to whom belongs the dominion of the heavens and the earth. There is no deity except Him; He gives life and causes death." So believe in Allāh and His Messenger, the unlettered prophet, who believes in Allāh and His words, and follow him that you may be guided.
Allah tells the Prophet (peace be upon him) to inform people that he is the messenger of Allah to them all, both Arabs and non-Arabs. Allah alone controls the heavens and the earth. There is nothing worthy of worship other than Him, glory be to Him. He brings the dead to life, and causes what is alive to die. People should have faith in Allah and in Muhammad (peace be upon him), the Prophet, His Messenger, who cannot read or write, and who came only with what His Lord revealed to him, in order to guide them to what is good for them in this world and in the Afterlife.
