Sahih Muslim , Book 4, Hadith 1716 (USC-MSA) ⓘ

'Urwa b. Zubair reported that 'A'isha, the wife of the Messenger of Allah, 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 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 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.

وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، وَمُحَمَّدُ بْنُ سَلَمَةَ الْمُرَادِيُّ، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم أَخْبَرَتْهُ أَنَّ الْحَوْلاَءَ بِنْتَ تُوَيْتِ بْنِ حَبِيبِ بْنِ أَسَدِ بْنِ عَبْدِ الْعُزَّى مَرَّتْ بِهَا وَعِنْدَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَقُلْتُ هَذِهِ الْحَوْلاَءُ بِنْتُ تُوَيْتٍ وَزَعَمُوا أَنَّهَا لاَ تَنَامُ اللَّيْلَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ تَنَامُ اللَّيْلَ خُذُوا مِنَ الْعَمَلِ مَا تُطِيقُونَ فَوَاللَّهِ لاَ يَسْأَمُ اللَّهُ حَتَّى تَسْأَمُوا ‏" ‏ ‏.‏
