Meghan Rose illustrates the progression of our entire life as the period between Adhan and Salah.

I was not born a Muslim, so I did not have this experience, but Alhamdulillah the adhan is one of the first things that I heard upon reverting. It goes on to say that when we die, the last thing that is said over us is the funeral prayer. So our lives begin with adhan and end with salah; our whole lives are lived between adhan and salah.
