'Urwa b. Zubair reported that 'A'isha, the wife of the Messenger of Allah (ﷺ), told him that (once) Haula' dint Tuwait b. Habib b. Asad b. 'Abd al-'Uzzi passed by her (at the time) when the Messenger of Allah (ﷺ) was with her. I ('A'Isha) said
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.
