It was narrated from Aishah that: The Prophet (ﷺ) came in to her and there was a woman with her. He said: "Who is this?" She said: "So-and-so, and she does not sleep." And she told him about how she prayed a great deal. He said: "Stop praising her. You should do what you can, for by Allah (SWT), Allah never gets tired (of giving reward) until you get tired. And the most beloved of religious actions to Him is that in which a person persists."
