وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ ابْنُ نُمَيْرٍ حَدَّثَنَا عُمَرُ بْنُ عُبَيْدٍ الطَّنَافِسِىُّ عَنْ سِمَاكِ بْنِ حَرْبٍ عَنْ مُوسَى بْنِ طَلْحَةَ عَنْ أَبِيهِ قَالَ كُنَّا نُصَلِّى وَالدَّوَابُّ تَمُرُّ بَيْنَ أَيْدِينَا فَذَكَرْنَا ذَلِكَ لِرَسُولِ اللَّهِ -صلى الله عليه وسلم- فَقَالَ « مِثْلُ مُؤْخِرَةِ الرَّحْلِ تَكُونُ بَيْنَ يَدَىْ أَحَدِكُمْ ثُمَّ لاَ يَضُرُّهُ مَا مَرَّ بَيْنَ يَدَيْهِ ». وَقَالَ ابْنُ نُمَيْرٍ « فَلاَ يَضُرُّهُ مَنْ مَرَّ بَيْنَ يَدَيْهِ ».

It was narrated from Musa bin Talhah that his father said: "We were offering Salat and animals were passing in front of us. We mentioned that to the Messenger of Allah (s.a.w) and he said: 'Let one of you put something like the back of a saddle in front of him, then it will not matter whatever passes in front of him."' Ibn Numair said: "It will not matter whoever passes in front of him."
