Sahih al-Bukhari 77:4
Narrated Abu Juhaifa:
I saw Bilal bringing a short spear (or stick) and fixing it in the ground, and then he proclaimed the Iqama of the prayer, and I saw Allah's Messenger (ﷺ) coming out, wearing a cloak with its sleeves rolled up. He then offered a two-rak`at prayer while facing the stick, and I saw the people and animals passing in front of him beyond the stick.

حَدَّثَنِي إِسْحَاقُ، أَخْبَرَنَا ابْنُ شُمَيْلٍ، أَخْبَرَنَا عُمَرُ بْنُ أَبِي زَائِدَةَ، أَخْبَرَنَا عَوْنُ بْنُ أَبِي جُحَيْفَةَ، عَنْ أَبِيهِ أَبِي جُحَيْفَةَ، قَالَ فَرَأَيْتُ بِلاَلاً جَاءَ بِعَنَزَةٍ فَرَكَزَهَا، ثُمَّ أَقَامَ الصَّلاَةَ، فَرَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ فِي حُلَّةٍ مُشَمِّرًا، فَصَلَّى رَكْعَتَيْنِ إِلَى الْعَنَزَةِ، وَرَأَيْتُ النَّاسَ وَالدَّوَابَّ يَمُرُّونَ بَيْنَ يَدَيْهِ مِنْ وَرَاءِ الْعَنَزَةِ.
