What are the four questions that would be asked on the Day of Judgment?

Prophet Muhammad  (ﷺ) is reported to have said:

“The feet of a servant will not move on the Day of Judgment until he has been questioned about four things): his life - how he spent it, his knowledge - how he acted upon it, his wealth - where he earned it and how he spent it, and his body - how he used it.”[1]
