Arabic hadith text
حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ، قَالَ سَمِعْتُ أَبِي أَنَّ النَّبِيَّ صلى الله عليه وسلمصَلَّى بِهِمْ بِالْبَطْحَاءِ ـ وَبَيْنَ يَدَيْهِ عَنَزَةٌ ـ الظُّهْرَ رَكْعَتَيْنِ، وَالْعَصْرَ رَكْعَتَيْنِ، تَمُرُّ بَيْنَ يَدَيْهِ الْمَرْأَةُ وَالْحِمَارُ.
Translation
Narrated `Aun bin Abi Juhaifa
I heard my father saying, "The Prophet (ﷺ) led us, and prayed a two-rak`at Zuhr prayer and then a tworak` at `Asr prayer at Al-Batha' [??] with a short spear (planted) in front of him (as a Sutra) while women and donkeys were passing in front of him (beyond that stick).
