وَعَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا
قَالَتْ: «كَانَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا دَخَلَ اَلْعَشْرُ (أَيْ: اَلْعَشْرُ اَلْأَخِيرُ مِنْ رَمَضَانَ) شَدَّ مِئْزَرَهُ، وَأَحْيَا لَيْلَهُ، وَأَيْقَظَ أَهْلَهُ»
Aishah (RAA) narrated, ‘With the start of the last ten days of Ramadan, the Messenger of Allah (sallallahu alayhi wa sallam) used to tighten his waist belt (i.e. keep away from his wives) and used to stay up praying all night, and he would also wake his wives (to pray and recite Qur’an etc.).’ Agreed upon.
