The Prophet ﷺ said: When one of you prays facing a sutrah he should keep close to it, and not let the devil interrupt his prayer. Abu Dawud said: This tradition has also been narrated by Waqid b. Muhammad from Safwan from Muhammad b. Sahl on the authority of his father, or on the authority of Muhammad b. Sahl from the Prophet ﷺ. Some have narrated it from Nafi' b. Jubair on the authority of Sahl b. Sa'd. There is a variation in the chain of its narrators.  

النَّبِيَّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ إِلَى سُتْرَةٍ فَلْيَدْنُ مِنْهَا لاَ يَقْطَعُ الشَّيْطَانُ عَلَيْهِ صَلاَتَهُ  

The distance between the place where the Prophet ﷺ stood and the qiblah (i.e. the sutrah or the wall of the mosque) was as much as to allow a goat to pass.  

وَكَانَ بَيْنَ مُقَامِ النَّبِيِّ ﷺ وَبَيْنَ الْقِبْلَةِ مَمَرُّ عَنْزٍ
