Mishkat al-Masabih 4 Prayer كتاب الصلاة 210

وَعَن سهل بن أبي حثْمَة قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا صَلَّى أَحَدُكُمْ إِلَى سُتْرَةٍ فَلْيَدْنُ مِنْهَا لَا يَقْطَعِ الشَّيْطَانُ عَلَيْهِ صَلَاتَهُ» . رَوَاهُ أَبُو دَاوُد

Sahl b. Abu Hathma reported God’s Messenger as saying, “When one of you prays facing a sutra * he should keep close to it and not let the devil interrupt his prayer.” * Sutra (covering, screen) is used of an object a worshipper places in front of him in the direction of the qibla when engaging in prayer. Abu Dawud transmitted it.
