سنن ابن ماجه

It was narrated that ‘Aishah said: “There was a woman with me, and the Prophet (ﷺ) entered upon me and said: ‘Who is that?’ I said: ‘So-and-so; she does not sleep,’” – she mentioned her excessive praying. “The Prophet (ﷺ) said: ‘Keep quiet. You should do what you are able to, for by Allah, Allah does not get tired (of giving reward) but you get tired.’” She said: “The most beloved of religious deed to him was that in which a person persists.”
