Abu Sa'id reported God's Messenger as saying, “No prophet is sent by God and no caliph succeeds another without having two close associates, one who commands and urges him to do what is reputable and one who commands and urges him to do what is evil. The one who is protected is he whom God protects.” Bukhari transmitted it.
