It was narrated that ‘Aishah said: “When the last ten days of Ramadan began, the Prophet used to stay up at night, tighten his waist- wrap, and wake up his family (to pray).”
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الزُّهْرِيُّ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ عُبَيْدِ بْنِ نِسْطَاسٍ، عَنْ أَبِي الضُّحَى، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ النَّبِيُّ ـ صلى الله عليه وسلم ـ إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا اللَّيْلَ وَشَدَّ الْمِئْزَرَ وَأَيْقَظَ أَهْلَهُ .
