Sahih Bukhari Volume 1, Book 8, Hadith 499

حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ حَدَّثَنَا عَوْنُ بْنُ أَبِي جُحَيْفَةَ، قَالَ سَمِعْتُ أَبِي قَالَ، خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم بِالْهَاجِرَةِ، فَأُتِيَ بِوَضُوءٍ فَتَوَضَّأَ فَصَلَّى بِنَا الظُّهْرَ وَالْعَصْرَ وَبَيْنَ يَدَيْهِ عَنَزَةٌ، وَالْمَرْأَةُ وَالْحِمَارُ يَمُرُّونَ مِنْ وَرَائِهَا

Narrated By 'Aun bin Abi Juhaifa : that he had heard his father saying, "Allah's Apostle came to us at mid-day and water was brought for his ablution. He performed ablution and led us in Zuhr and 'Asr prayers with an 'Anza planted in front of him (as a Sutra), while women and donkeys were passing beyond it."
