I think this khutbah sends a good message across about competition and our obsession with comparing ourselves to others.
In this world where comparing is rampant where everyone just wants to up-one the other, that obsession has begun to drain our souls. Even in the path of service to Allah SWT, we compete. This is not the right mindset. Instead, what we need is to shift that mindset from attempting to compete against someone else to competing with our own selves. To take their success as a motivator for us to better ourselves.
