It was narrated that Aisha (RA) 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." (Sahih)
