in Edition Clear Qur'an by Talal Itani / Al-A'raaf (The Heights)

7:157Those who follow the Messenger, the Unlettered Prophet, whom they find mentioned in the Torah and the Gospel in their possession. He directs them to righteousness, and deters them from evil, and allows for them all good things, and prohibits for them wickedness, and unloads the burdens and the shackles that are upon them. Those who believe in him, and respect him, and support him, and follow the light that came down with him—these are the successful.

7:158Say, “O people, I am the Messenger of God to you all—He to whom belongs the kingdom of the heavens and the earth. There is no god but He. He gives life and causes death.” So believe in God and His Messenger, the Unlettered Prophet, who believes in God and His words. And follow him, that you may be guided.
