Umar said to Abu Bakr, "You are the best of people after the Messenger of Allah."Abu Bakr replied, "If you say that, then indeed I heard the Messenger of Allah ﷺ say, 'The sun has not risen upon a man better than Umar.'"
حدثنا محمد بن المثنى حدثنا عبد الله بن داود الواسطي أبو محمد حدثني عبد الرحمن ابن أخي محمد بن المنكدر عن محمد بن المنكدر

[Its chain is daif] Hakim narrated it: 1/90 from the hadith of Abdullah bin Dawud Wasiti through this route, and said, "Its chain is sahih," but Dhahabi said, "Abdullah was declared daif by scholars, and Abdul-Rahman Qurashi Tamimi has been criticized, and the hadith is virtually fabricated."There is also a narration on this subject from Abu Darda [Khatib: 12/438, in which it has Abu Bakr instead of Umar].
