nasai:686Muḥammad b. ʿAbdullāh b. ʿAbd al-Ḥakam > Shuʿayb > al-Layth > Khālid > Ibn Abū Hilāl > Makhramah b. Sulaymān > Kurayb a freed slave of Ibn ʿAbbās

"I asked Ibn 'Abbas: 'How did the Messenger of Allah ﷺ pray at night?' He said: 'He prayed eleven Rak'ahs including Witr, then he slept deeply until I could hear him snoring, then Bilal came to him and said: "The prayer, O Messenger of Allah!" Then he got up and prayed two brief Rak'ahs then led the people in prayer, and he did not perform Wudu'.'"  

النسائي:٦٨٦أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عَبْدِ الْحَكَمِ عَنْ شُعَيْبٍ عَنِ اللَّيْثِ قَالَ حَدَّثَنَا خَالِدٌ عَنِ ابْنِ أَبِي هِلاَلٍ عَنْ مَخْرَمَةَ بْنِ سُلَيْمَانَ أَنَّ كُرَيْبًا مَوْلَى ابْنِ عَبَّاسٍ

أَخْبَرَهُ قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ قُلْتُ كَيْفَ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ بِاللَّيْلِ فَوَصَفَ أَنَّهُ صَلَّى إِحْدَى عَشْرَةَ رَكْعَةً بِالْوِتْرِ ثُمَّ نَامَ حَتَّى اسْتَثْقَلَ فَرَأَيْتُهُ يَنْفُخُ وَأَتَاهُ بِلاَلٌ فَقَالَ الصَّلاَةُ يَا رَسُولَ اللَّهِ فَقَامَ فَصَلَّى رَكْعَتَيْنِ وَصَلَّى بِالنَّاسِ وَلَمْ يَتَوَضَّأْ

الكبرى للنسائي:١٦٦٢أَخْبَرَنِي مُحَمَّدُ بْنُ عَبْدِ اللهِ بْنِ عَبْدِ الْحَكَمِ عَنْ شُعَيْبٍ قَالَ حَدَّثَنَا اللَّيْثُ قَالَ حَدَّثَنَا خَالِدٌ عَنِ ابْنِ أَبِي هِلَالٍ عَنْ مَخْرَمَةَ بْنِ سُلَيْمَانَ أَنَّ كُرَيْبًا مَوْلَى ابْنِ عَبَّاسٍ

أَخْبَرَهُ قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ قُلْتُ كَيْفَ كَانَتْ صَلَاةُ رَسُولِ اللهِ ﷺ بِاللَّيْلِ؟ فَوَصَفَ أَنَّهُ «صَلَّى إِحْدَى عَشْرَةَ رَكْعَةً بِالْوِتْرِ ثُمَّ نَامَ حَتَّى اسْتَثْقَلَ فَرَأَيْتُهُ يَنْفُخُ» فَأَتَاهُ بِلَالٌ فَقَالَ الصَّلَاةَ يَا رَسُولَ اللهِ «فَقَامَ فَصَلَّى رَكْعَتَيْنِ وَصَلَّى لِلنَّاسِ وَلَمْ يَتَوَضَّأْ»
