أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا دَاوُدُ، عَنْ عَمْرٍو، عَنْ كُرَيْبٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ صَلَّيْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم ذَاتَ لَيْلَةٍ فَقُمْتُ عَنْ يَسَارِهِ فَجَعَلَنِي عَنْ يَمِينِهِ فَصَلَّى ثُمَّ اضْطَجَعَ وَرَقَدَ فَجَاءَهُ الْمُؤَذِّنُ فَصَلَّى وَلَمْ يَتَوَضَّأْ مُخْتَصَرٌ ‏.‏

It was narrated that Ibn 'Abbas said: "I prayed with the Prophet (PBUH) one night, and I stood on his left, but he made me stand on his right, and he prayed. Then he reclined on his side and took a nap, then the Mu'adhdhin came to him and he prayed, and did not perform Wudu'." Translation Not Available
