“The Prophet ﷺ used to strive hard (in worship) in the last ten nights of Ramadan as he never did at any other time.”  

كَانَ النَّبِيُّ ﷺ يَجْتَهِدُ فِي الْعَشْرِ الأَوَاخِرِ مَا لاَ يَجْتَهِدُ فِي غَيْرِهِ  

“When the last ten days of Ramadan began, the Prophet ﷺ used to stay up at night, tighten his waist- wrap, and wake up his family (to pray).”  

كَانَ النَّبِيُّ ﷺ إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا اللَّيْلَ وَشَدَّ الْمِئْزَرَ وَأَيْقَظَ أَهْلَهُ
