Sahih Bukhari Volume 1, Book 9, Hadith Number 474

Narated By ‘Aun bin Abi Juhaifa : I heard my father saying, “The Prophet led us, and prayed a two-Rak’at Zuhr prayer and then a two-Rak’at ‘Asr prayer at Al-Batha’ with an ‘Anza (planted) in front of him (as a Sutra) while women and donkeys were passing in front of him (beyond that ‘Anza).”
