Thus, We inspired to you a revelation of Our command. You did not know what the book was, nor the acknowledgement. Yet, We made this a light to guide whomever We wish from among Our servants. Surely, you guide to a straight path.

[42:52] For more information about ruh, see 17:85; 15:29. None can guide anyone to salvation, including Jesus and Muhammed. Verse 28:56 states that Muhammed could not guide those he loved. But it was up to God to choose those who deserve to be guided. Muhammed could guide people in accordance to God's preestablished laws, but he could not guide a particular person of his choice. Every monotheist can guide to the "right path" defined by God. In other words, it is God who defines the system and condiditions of guidance, and we are expected to deliver it to others. Accepting Muhammed as independent source of guidance is setting him up as a partner with God. See 6:112-114; 39:11. Also, see 7:30; 28:56.
