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 Messenger of Allah ﷺ coming out, wearing a cloak with its sleeves rolled up. He then offered a two-rakʿat prayer while facing the stick, and I saw the people and animals passing in front of him beyond the stick.  

فَرَأَيْتُ بِلاَلاً جَاءَ بِعَنَزَةٍ فَرَكَزَهَا ثُمَّ أَقَامَ الصَّلاَةَ فَرَأَيْتُ رَسُولَ اللَّهِ ﷺ خَرَجَ فِي حُلَّةٍ مُشَمِّرًا فَصَلَّى رَكْعَتَيْنِ إِلَى الْعَنَزَةِ وَرَأَيْتُ النَّاسَ وَالدَّوَابَّ يَمُرُّونَ بَيْنَ يَدَيْهِ مِنْ وَرَاءِ الْعَنَزَةِ
