وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي عَطَاءٌ، عَنِ ابْنِ عَبَّاسٍ، قَالَ بِتُّ ذَاتَ لَيْلَةٍ عِنْدَ خَالَتِي مَيْمُونَةَ فَقَامَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي مُتَطَوِّعًا مِنَ اللَّيْلِ فَقَامَ النَّبِيُّ صلى الله عليه وسلم إِلَى الْقِرْبَةِ فَتَوَضَّأَ فَقَامَ فَصَلَّى فَقُمْتُ لَمَّا رَأَيْتُهُ صَنَعَ ذَلِكَ فَتَوَضَّأْتُ مِنَ الْقِرْبَةِ ثُمَّ قُمْتُ إِلَى شِقِّهِ الأَيْسَرِ فَأَخَذَ بِيَدِي مِنْ وَرَاءِ ظَهْرِهِ يَعْدِلُنِي كَذَلِكَ مِنْ وَرَاءِ ظَهْرِهِ إِلَى الشِّقِّ الأَيْمَنِ . قُلْتُ أَفِي التَّطَوُّعِ كَانَ ذَلِكَ قَالَ نَعَمْ .
Ibn `Abbas reported:I spent a night in the house of my mother's sister Maimuna. The Apostle of Allah (ﷺ) got up for observing voluntary prayer (Tahajjud) at night. The Apostle of Allah (ﷺ) stood by the water-skin and performed ablution and then stood up and prayed. I also got up when I saw him doing that. I also performed ablution from the water-skin and then stood at his left side. He took hold of my hand from behind his back and then turned me from his back to his right side. I (`Ata', one of the narrators) said: Did it concern the voluntary prayer (at night)? He (Ibn `Abbas) said: Yes
