Sahih Bukhari Volume 4, Book 61, Hadith 3568

حَدَّثَنَا الْحَسَنُ بْنُ الصَّبَّاحِ، حَدَّثَنَا مُحَمَّدُ بْنُ سَابِقٍ، حَدَّثَنَا مَالِكُ بْنُ مِغْوَلٍ، قَالَ سَمِعْتُ عَوْنَ بْنَ أَبِي جُحَيْفَةَ، ذَكَرَ عَنْ أَبِيهِ، قَالَ دُفِعْتُ إِلَى النَّبِيِّ صلى الله عليه وسلم وَهْوَ بِالأَبْطَحِ فِي قُبَّةٍ كَانَ بِالْهَاجِرَةِ، خَرَجَ بِلاَلٌ فَنَادَى بِالصَّلاَةِ، ثُمَّ دَخَلَ فَأَخْرَجَ فَضْلَ وَضُوءِ رَسُولِ اللَّهِ صلى الله عليه وسلم، فَوَقَعَ النَّاسُ عَلَيْهِ يَأْخُذُونَ مِنْهُ، ثُمَّ دَخَلَ فَأَخْرَجَ الْعَنَزَةَ، وَخَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ سَاقَيْهِ فَرَكَزَ الْعَنَزَةَ، ثُمَّ صَلَّى الظُّهْرَ رَكْعَتَيْنِ وَالْعَصْرَ رَكْعَتَيْنِ، يَمُرُّ بَيْنَ يَدَيْهِ الْحِمَارُ وَالْمَرْأَةُ‏

Narrated By Abu Juhaifa : By chance I went to the Prophet at noon while he was at Al-Abtah (resting) in a tent. Bilal came out (of the tent) and pronounced the Adhan for the prayer, and entering again, he brought out the water which was left after Allah's Apostle had performed the ablution. The people rushed to take some of the water. Bilal again went in and brought out a spear-headed stick, and then Allah's Apostle came out. As if I were now looking at the whiteness of his leg. Bilal fixed the stick and the Prophet offered a two-Rakat Zuhr prayer and a two-Rak'at 'Asr prayer, while women and donkeys were passing in front of the Prophet (beyond the stick).
