Sahih al-Bukhari · Book 32: Virtues of the Night of Qadr · Good deeds in the last ten days of Ramadan.
Narrated Aisha:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ أَبِي يَعْفُورٍ ، عَنْ أَبِي الضُّحَى ، عَنْ مَسْرُوقٍ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا دَخَلَ الْعَشْرُ شَدَّ مِئْزَرَهُ، وَأَحْيَا لَيْلَهُ، وَأَيْقَظَ أَهْلَهُ.
With the start of the last ten days of Ramadan, the Prophet (ﷺ) used to tighten his waist belt (i.e. work hard) and used to pray all the night, and used to keep his family awake for the prayers.
