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.  

كَانَ النَّبِيُّ ﷺ إِذَا دَخَلَ الْعَشْرُ شَدَّ مِئْزَرَهُ وَأَحْيَا لَيْلَهُ وَأَيْقَظَ أَهْلَهُ  

'A'isha (Allah be pleased with her) reported that when the last ten nights began Messenger of Allah ﷺ kept awake at night (for prayer and devotion), wakened his family, and prepared himself to observe prayer (with more vigour).  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْعَشْرُ أَحْيَا اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَجَدَّ وَشَدَّ الْمِئْزَرَ  

"Aishah may Allah (SWT) be pleased with her, said: ' When the last ten nights of Ramadan began, the Messenger of Allah ﷺ stayed up at night (for prayer) and he woke his family up and tightened his waist-wrap.'"  

عَائِشَةُ ؓ كَانَ إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا رَسُولُ اللَّهِ ﷺ اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ  

When the last ten days of Ramadan came, the Prophet ﷺ kept vigil and prayed during the whole night, and tied the wrapper tightly, and awakened his family (to pray during the night). Abu Dawud said: The name of Abu Ya'fur is 'Abd al-Rahman b. 'Ubaid b. Nistas.  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا دَخَلَ الْعَشْرُ أَحْيَا اللَّيْلَ وَشَدَّ الْمِئْزَرَ وَأَيْقَظَ أَهْلَهُ  

[Machine] The Prophet ﷺ used to revive the night and wake up his family when the last ten days of Ramadan entered, and he would tighten his waistcloth. Sufyan said, and one of the scholars said.  

عَنِ النَّبِيِّ ﷺ كَانَ إِذَا دَخَلَ الْعَشْرُ أَحْيَا اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ قَالَ سُفْيَانُ وَوَاحِدَةٌ مِنْ آخِرِ وَجَدَّ  

“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).” (Using translation from Ibn Mājah 1768)  

«كَانَ النَّبِيُّ ﷺ إِذَا دَخَلَ الْعَشْرُ أَيْقَظَ أَهْلَهُ وأَحْيَى اللَّيْلَ وَشَدَّ الْمِئْزَرَ»  

[Machine] "When the Prophet Muhammad ﷺ entered the last ten nights of Ramadan, he used to wake up his family, tighten his waist belt, and stay up all night in worship."  

«كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْعَشْرُ الْأَوَاخِرُ مِنْ رَمَضَانَ أَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ وَأَحْيَا اللَّيْلَ»  

'A'isha (Allah be pleased with her) reported that when the last ten nights began Messenger of Allah ﷺ kept awake at night (for prayer and devotion), wakened his family, and prepared himself to observe prayer (with more vigour). (Using translation from Muslim 1174)  

«كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْعَشْرُ أَحْيَا اللَّيْلَ وَشَدَّ الْمِئْزَرَ وَأَيْقَظَ أَهْلَهُ»  

"Aishah may Allah (SWT) be pleased with her, said: ' When the last ten nights of Ramadan began, the Messenger of Allah ﷺ stayed up at night (for prayer) and he woke his family up and tightened his waist-wrap.'" (Using translation from Nasāʾī 1639)  

عَائِشَةُ كَانَ «إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا رَسُولُ اللهِ ﷺ اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ»  

"Aishah may Allah (SWT) be pleased with her, said: ' When the last ten nights of Ramadan began, the Messenger of Allah ﷺ stayed up at night (for prayer) and he woke his family up and tightened his waist-wrap.'" (Using translation from Nasāʾī 1639)  

عَائِشَةُ «كَانَتْ إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا رَسُولُ اللهِ ﷺ اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ»  

"عَنْ عَائِشَةَ: أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا دَخَلَ العَشْرُ الأَوَاخِرُ أَيْقَظَ أَهْلَهُ، وَأَحْيَا اللَّيْلَ، وَشَدَّ المِئْزَرَ".
