Once I came riding a she-ass when I had just attained the age of puberty. Messenger of Allah ﷺ was offering the prayer at Mina with no wall in front of him and I passed in front of some of the row. There I dismounted and let my she-ass loose to graze and entered the row and nobody objected to me about it.  

أَنَّهُ قَالَ أَقْبَلْتُ رَاكِبًا عَلَى حِمَارٍ أَتَانٍ وَأَنَا يَوْمَئِذٍ قَدْ نَاهَزْتُ الاِحْتِلاَمَ وَرَسُولُ اللَّهِ ﷺ يُصَلِّي بِالنَّاسِ بِمِنًى إِلَى غَيْرِ جِدَارٍ فَمَرَرْتُ بَيْنَ يَدَىْ بَعْضِ الصَّفِّ فَنَزَلْتُ وَأَرْسَلْتُ الأَتَانَ تَرْتَعُ وَدَخَلْتُ فِي الصَّفِّ فَلَمْ يُنْكِرْ ذَلِكَ عَلَىَّ أَحَدٌ  

Whenever Messenger of Allah ﷺ came out on ʿId day, he used to order that a Harba [??] (a short spear) to be planted in front of him (as a Sutra for his prayer) and then he used to pray facing it with the people behind him and used to do the same while on a journey. After the Prophet ﷺ , this practice was adopted by the Muslim rulers (who followed his traditions).  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا خَرَجَ يَوْمَ الْعِيدِ أَمَرَ بِالْحَرْبَةِ فَتُوضَعُ بَيْنَ يَدَيْهِ فَيُصَلِّي إِلَيْهَا وَالنَّاسُ وَرَاءَهُ وَكَانَ يَفْعَلُ ذَلِكَ فِي السَّفَرِ فَمِنْ ثَمَّ اتَّخَذَهَا الأُمَرَاءُ  

I heard my father saying, "The Prophet ﷺ led us, and prayed a two-rakʿat Zuhr prayer and then a tworakʿ at ʿAsr 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).  

أَنَّ النَّبِيَّ ﷺ صَلَّى بِهِمْ بِالْبَطْحَاءِ وَبَيْنَ يَدَيْهِ عَنَزَةٌ الظُّهْرَ رَكْعَتَيْنِ وَالْعَصْرَ رَكْعَتَيْنِ تَمُرُّ بَيْنَ يَدَيْهِ الْمَرْأَةُ وَالْحِمَارُ
