Ayesha reported,

The Prophet ﷺ came to visit her while a woman was with her. He asked, "Who is this?"She replied, "So-and-so. She does not sleep, due to how much she prays."He said, "Stop. Take on only as much worship as you can sustain. By Allah, Allah عز وجل does not tire until you tire." The dearest form of religious practice to him was what a person could maintain consistently.
