The Messenger of Allah ﷺ said: When one of you places in front of him so me. thing such as the back of a saddle, he should pray without caring who passes on the other side of it.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا وَضَعَ أَحَدُكُمْ بَيْنَ يَدَيْهِ مِثْلَ مُؤْخِرَةِ الرَّحْلِ فَلْيُصَلِّ وَلاَ يُبَالِ مَنْ مَرَّ وَرَاءَ ذَلِكَ  

When you place in front of you something such as the back of a saddle, then there is no harm if someone passes in front of you (i.e. the other side of it).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا جَعَلْتَ بَيْنَ يَدَيْكَ مِثْلَ مُؤَخَّرَةِ الرَّحْلِ فَلاَ يَضُرُّكَ مَنْ مَرَّ بَيْنَ يَدَيْكَ  

“We used to perform prayer while the beasts were passing in front of us. That was mentioned to the Messenger of Allah ﷺ and he said: ‘If something like the hand of a saddle* is placed in front of anyone of you, it will not matter whoever passes in front of him.” * It is the piece of wood on the camel saddle which is held on to (to climb onto the camel).  

كُنَّا نُصَلِّي وَالدَّوَابُّ تَمُرُّ بَيْنَ أَيْدِينَا فَذُكِرَ ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَقَالَ مِثْلُ مُؤْخِرَةِ الرَّحْلِ تَكُونُ بَيْنَ يَدَىْ أَحَدِكُمْ فَلاَ يَضُرُّهُ مَنْ مَرَّ بَيْنَ يَدَيْهِ  

“Let one of you put something in front of him the height of the back of a saddle, then pray.ʿ  

أَنَّ النَّبِيَّ ﷺ قَالَ يَجْعَلُ أَحَدُكُمْ بَيْنَ يَدَيْهِ مِثْلَ مُؤْخِرَةِ الرَّحْلِ ثُمَّ يُصَلِّي  

The Messenger of Allah ﷺ said: When one of you places in front of him so me. thing such as the back of a saddle, he should pray without caring who passes on the other side of it. (Using translation from Muslim 499a)  

قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا وَضَعَ أَحَدُكُمْ بَيْنَ يَدَيْهِ مِثْلُ مُؤْخِرَةِ الرَّحْلِ فَلْيُصَلِّ وَلَا يُبَالِي مَنْ مَرَّ وَرَاءَ ذَلِكَ»  

"إذا كانَ بينَكَ وبينَ مَنْ يمرُّ بينَ يديكَ مِثلُ مؤَخِّرةِ الرَّحْلِ فقد سَتركَ".  

"لِيَضَعْ أحَدُكُمْ بَينَ يَدَيهِ مِثْلَ مُؤَخِّرَةِ الرَّحْلِ، وَلَا يَضُرُّه مَا مَر بَين يَدَيهِ".
