The authenticity of the report from 'Umar regarding a man saying, "I am a believer"

Question:
What is the authenticity of what Imam Ahmad narrated from 'Umar that he said: "Whoever says, 'I am a believer,' is a disbeliever; whoever says, 'I am a scholar,' is ignorant; and whoever says, 'I am in Paradise,' is in the Fire. If this is authentic, what is the meaning of this statement?"

Answer:
This is well known from 'Umar, but I do not recall the status of its chain of narration right now. However, it is well known. His intention was that it is not befitting for one to certify his own faith. It is not befitting for him to be humble before Allah and certify himself by saying, "I am a believer" or "I am a scholar." It is befitting for him to do so, which is why the Salaf used to say, "I am a believer, if Allah wills." And the scholar would say, "I am a student of knowledge; I am knowledgeable about such and such," so as not to certify himself. It is befitting for him to be humble. So 'Umar's intention was humility before Allah and not certifying oneself. This is a required matter, whether it is authentic from 'Umar or not. It is required of the believer to be humble and not certify himself. Allah says: And the Salaf, when asked, "Is he a believer?" would say, "If Allah wills," because he does not know if his faith is complete or if his faith is not complete. Some of them consider the ending of their lives; they do not know on what they will die. And some of them say, "I am a believer " And many people answer the questioner, even though asking this question is not prescribed. It is not prescribed for you to say, "I am a believer," and you have no right to ask a worshipper. But if a person is asked and says, "He is a believer, if Allah wills," that is not blameworthy; it is out of scrupulousness and out of caution. Yes.
