The Sutra (screen) of one who is praying

It was narrated that Aisha(ra) said:

"The messenger of Allah(ﷺ) was asked during the campaign of Tabuk about the Sutra of one who is praying. He said: "Something as high as the back of a camel saddle."

أَخْبَرَنَا الْعَبَّاسُ بْنُ مُحَمَّدٍ الدُّورِيُّ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَزِيدَ، قَالَ حَدَّثَنَا حَيْوَةُ بْنُ شُرَيْحٍ، عَنْ أَبِي الأَسْوَدِ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي غَزْوَةِ تَبُوكَ عَنْ سُتْرَةِ الْمُصَلِّي فَقَالَ ‏

‏ مِثْلُ مُؤْخِرَةِ الرَّحْلِ ‏

‏ ‏.‏

Narrated Ibn Umar:

It was narrated from Ibn Umar concerning the Messenger of Allah (ﷺ) he said: "He used to set up a short spear then pray facing toward it."

أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ أَنْبَأَنَا نَافِعٌ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ كَانَ يَرْكُزُ الْحَرْبَةَ ثُمَّ يُصَلِّي إِلَيْهَا ‏.‏
