Sahih Muslim Book - 6, Hadith - 1833

وَحَدَّثَنِى حَرْمَلَةُ بْنُ يَحْيَى وَمُحَمَّدُ بْنُ سَلَمَةَ الْمُرَادِىُّ قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ عَنْ يُونُسَ عَنِ ابْنِ شِهَابٍ قَالَ أَخْبَرَنِى عُرْوَةُ بْنُ الزُّبَيْرِ أَنَّ عَائِشَةَ زَوْجَ النَّبِىِّ -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 ».

'Urwah bin Az-Zubair narrated that 'Aishah, the wife of the Prophet (s.a.w), told him that AI-Hawla' bint Tuwait bin Habib bin Asad bin 'Abdul' Uzza passed by her and the Messenger of Allah (s.a.w) was with her. I said: "This is AI-Hawla' bint Tuwait; they say that she does not sleep at night." The Messenger of Allah (s.a.w) said: "She does not sleep at night! Do as much as you are able to, for by Allah, Allah does not grow weary but you do."
