The authenticity of the report from 'Umar regarding the statement: "I am a believer, and its meaning"

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

Answer:
This is well known from 'Umar, but I do not know the state of its chain; however, it is well known. His intention is that one should not certify oneself as righteous; one should not certify oneself as righteous; one should be humble before Allah and not certify oneself by saying "I am a believer" or "I am a scholar." One should, for this reason, the Salaf would 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. He should be humble. So 'Umar's intention was humility before Allah and not certifying oneself, and this is required whether it is authentic from 'Umar or not. It is required of the believer to be humble and not certify himself. Allah says: When the Salaf were asked, "Is he a believer?" they would say, "If Allah wills," meaning 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 what they will die upon. And some of them would say "I am a believer" and a great deal more, answering the questioner, even though this question is not prescribed. It is not prescribed for you to say "I am a believer," and you have no right to ask people, but if a person is asked and says "The believers, if Allah wills," there is no blame on him from the standpoint of scrupulousness, from the standpoint of caution. Yes.
