Musannaf Ibn Abi Shayba 23:105

Ibn Idris narrated to us, from Muhammad ibn Ishaq, from Sa’id ibn Yasar, who said: It reached Umar that a man in al-Sham claimed that he was a believer. He said: So Umar wrote, "Bring him to me." He arrived before Umar, and he said, "Are you the one who claims that you are a believer?" He said, "Were the people during the time of the Messenger of Allah, may Allah bless him and grant him peace, anything other than three stations: a believer, a disbeliever, and a hypocrite? By Allah, I am neither a disbeliever nor a hypocrite." Umar said to him, "Extend your hand." Ibn Idris said: I said, "He was satisfied with what he said." He said, "He was satisfied with what he said."
