question #3 Sahih Muslim 785a, Book 6, Hadith 261 : Why is it important to balance one’s acts of worship with their personal capacity?

It Is Haula’ bint Tuwait and they say that she does not sleep at night. Upon this the Messenger of Allah (ﷺ) said: (Oh) she does not sleep at night! Choose an act which you are capable of doing (continuously). By Allah, Allah would not grow weary, but you will grow weary.
