Ayesha reported,

The Prophet ﷺ came in to visit her while a woman was with her. He asked, "Who is this?"She replied, "This is so-and-so," and mentioned how much she prayed.He said, "Stop. You should only take on what you can sustain. By Allah, Allah does not tire until you tire." And the most beloved form of religious practice to him was that which a person could maintain consistently.
