Narrated Nafi`:

"The Prophet (ﷺ) used to make his she-camel sit across and he would pray facing it (as a Sutra)." I asked, "What would the Prophet (ﷺ) do if the she-camel was provoked and moved?" He said, "He would take its camel-saddle and put it in front of him and pray facing its back part (as a Sutra). And Ibn `Umar used to do the same." (This indicates that one should not pray except behind a Sutra).

حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ الْمُقَدَّمِيُّ، حَدَّثَنَا مُعْتَمِرٌ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ يُعَرِّضُ رَاحِلَتَهُ فَيُصَلِّي إِلَيْهَا‏.‏ قُلْتُ أَفَرَأَيْتَ إِذَا هَبَّتِ الرِّكَابُ‏.‏ قَالَ كَانَ يَأْخُذُ هَذَا الرَّحْلَ فَيُعَدِّلُهُ فَيُصَلِّي إِلَى آخِرَتِهِ ـ أَوْ قَالَ مُؤَخَّرِهِ ـ وَكَانَ ابْنُ عُمَرَ ـ رضى الله عنه ـ يَفْعَلُهُ‏.‏

Prayer is a connection between a person and his Lord, in which the worshipper stands and converses with his Lord, facing towards Him. Islam enjoins focusing with proper humility (khushu‘) in prayer, and not being distracted, and sets out guidelines concerning that both for the worshipper and the one who is not praying, so that the prayer will not be interrupted and the humble focus (khushu‘) will not be disrupted by the action of either of them. In this hadith, ‘Abdullah ibn ‘Umar (may Allah be pleased with him) narrates that the Prophet (blessings and peace of Allah be upon him) used to stand with his mount – meaning the camel that he used to ride – in front of him, perpendicular to it, and he would use it as a sutrah (screen), facing towards it. It was said to Nafi‘ – who was the one who narrated the report from Ibn ‘Umar: What if the mount would not sit still? In other words, what if the camel jumped up and distracted the worshipper because it did not stay still – what should he do? Nafi‘ said: The Prophet (blessings and peace of Allah be upon him) would take the saddle, which was something that would be tied to the camel’s back to give the rider a place to sit, so that if the camel jumped up and he could not pray facing towards it – he would take the saddle as a sutrah instead of the mount, and he would pray facing towards the back of the saddle. This hadith indicates that it is permissible to use an animal as a sutrah when praying. It also indicates that it is permissible to pray near a camel; this is a different matter to praying in camel pens, as there are sahih hadiths which prohibit doing that..
