Ibn `Abbas reported:I spent one night in the house of my mother's sister Maimuna, daughter of Al-Harith, and said to her: Awake me when the Messenger of Allah (ﷺ) stands to pray (at night). (She woke me up when) the Messenger of Allah (ﷺ) stood up for prayer. I stood on his left side. He took hold of my hand and made me stand on his right side, and whenever I dozed off he took hold of my earlobe (and made me alert). He (the narrator) said: He (the Holy Prophet) observed eleven rak`ahs. He then sat with his legs drawn and wrapped in his garment and slept so that I could hear his breathing while asleep. And when the dawn appeared, he observed two short rak`ahs of (Sunnah) prayer.
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ، أَخْبَرَنَا الضَّحَّاكُ، عَنْ مَخْرَمَةَ بْنِ سُلَيْمَانَ، عَنْ كُرَيْبٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ، قَالَ بِتُّ لَيْلَةً عِنْدَ خَالَتِي مَيْمُونَةَ بِنْتِ الْحَارِثِ فَقُلْتُ لَهَا إِذَا قَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَأَيْقِظِينِي . فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقُمْتُ إِلَى جَنْبِهِ الأَيْسَرِ فَأَخَذَ بِيَدِي فَجَعَلَنِي مِنْ شِقِّهِ الأَيْمَنِ فَجَعَلْتُ إِذَا أَغْفَيْتُ يَأْخُذُ بِشَحْمَةِ أُذُنِي - قَالَ - فَصَلَّى إِحْدَى عَشْرَةَ رَكْعَةً ثُمَّ احْتَبَى حَتَّى إِنِّي لأَسْمَعُ نَفَسَهُ رَاقِدًا فَلَمَّا تَبَيَّنَ لَهُ الْفَجْرُ صَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ .
