Sahih Muslim Book - 6, Hadith - 1792

وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ حَدَّثَنَا ابْنُ أَبِى فُدَيْكٍ أَخْبَرَنَا الضَّحَّاكُ عَنْ مَخْرَمَةَ بْنِ سُلَيْمَانَ عَنْ كُرَيْبٍ مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ قَالَ بِتُّ لَيْلَةً عِنْدَ خَالَتِى مَيْمُونَةَ بِنْتِ الْحَارِثِ فَقُلْتُ لَهَا إِذَا قَامَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَأَيْقِظِينِى. فَقَامَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَقُمْتُ إِلَى جَنْبِهِ الأَيْسَرِ فَأَخَذَ بِيَدِى فَجَعَلَنِى مِنْ شِقِّهِ الأَيْمَنِ فَجَعَلْتُ إِذَا أَغْفَيْتُ يَأْخُذُ بِشَحْمَةِ أُذُنِى - قَالَ - فَصَلَّى إِحْدَى عَشْرَةَ رَكْعَةً ثُمَّ احْتَبَى حَتَّى إِنِّى لأَسْمَعُ نَفَسَهُ رَاقِدًا فَلَمَّا تَبَيَّنَ لَهُ الْفَجْرُ صَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ.

It was narrated that Ibn 'Abbas said: "I stayed one night with my maternal aunt Maimunah bint Al-Harith, and I said to her: 'When the Messenger of Allah (s.a.w) gets up, wake me up.' The Messenger of Allah (s.a.w) got up and I stood on his left side. He took me by the hand and made me stand on his right side. If I dozed off, he would take hold of my earlobe. He prayed eleven Rak'ah, then he sat with his legs drawn up to his chest, wrapped in his garment, until I could hear his breathing as he slept. When dawn came, he prayed two brief Rak'ah."
