158. Say, [O Muhammad]: “O people, I am the Messenger of Allāh to you all, the One to Whom belongs the dominion of the heavens and the earth. There is no god worthy of worship 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, so that you may be rightly guided [35].”
[35]. If you declare with your tongue, “There is no god but Allāh, and Muhammad is His servant and Messenger,” and truly believe it in your heart, you will be saved from the Hellfire and admitted into Paradise.
