I said to my father: Which of the people after the Messenger of Allah (ﷺ) is best? He replied: Abu Bakr. I then asked: Who comes next? He said: ‘Umar. I was then afraid of asking him who came next, and he might mention ‘Uthman, so I said: You came next, O my father? He said: I am only a man among the Muslims.
