Sahih Muslim Book - 3, Hadith - 830

و حَدَّثَنِي مُحَمَّدُ بْنُ عَمْرِو بْنِ عَبَّادِ بْنِ جَبَلَةَ حَدَّثَنَا أَبُو عَاصِمٍ عَنْ ابْنِ جُرَيْجٍ قَالَ حَدَّثَنَا سَعِيدُ بْنُ حُوَيْرِثٍ أَنَّهُ سَمِعَ ابْنَ عَبَّاسٍ يَقُولُ إِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَضَى حَاجَتَهُ مِنْ الْخَلَاءِ فَقُرِّبَ إِلَيْهِ طَعَامٌ فَأَكَلَ وَلَمْ يَمَسَّ مَاءً. قَالَ وَزَادَنِي عَمْرُو بْنُ دِينَارٍ عَنْ سَعِيدِ بْنِ الْحُوَيْرِثِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قِيلَ لَهُ إِنَّكَ لَمْ تَوَضَّأْ قَالَ مَا أَرَدْتُ صَلَاةً فَأَتَوَضَّأَ وَزَعَمَ عَمْرٌو أَنَّهُ سَمِعَ مِنْ سَعِيدِ بْنِ الْحُوَيْرِثِ.

Sa'eed bin Al-Huwairith narrated that he heard Ibn 'Abbas say: "The Prophet (s.a.w) relieved himself, then some food was brought to him, and he ate and did not touch water." (The narrator) said: "'Amr bin Dinar added, narrating from Sa'eed bin Al-Huwairith, that it was said to the Prophet (s.a.w): 'Are you not going to perform Wudu'?' He said: 'I am not going to prayer, that I should do Wudu'?' 'Amr claimed that he heard this from Sa'eed bin Al-Huwairith."
