وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا صَلَّى أَحَدُكُمْ فَلْيَجْعَلْ تِلْقَاءَ وَجْهِهِ شَيْئًا فَإِنْ لَمْ يَجِدْ فَلْيَنْصِبْ عَصَاهُ فَإِنْ لَمْ يَكُنْ مَعَهُ عَصَى فَلْيَخْطُطْ خَطًّا ثُمَّ لَا يَضُرُّهُ مَا مَرَّ أَمَامه» . رَوَاهُ أَبُو دَاوُد وَابْن مَاجَه

Al-Fadl b. ‘Abbas said, “God’s Messenger came to us accompanied by ‘Abbas when we were in open country belonging to us. He prayed in a desert with no sutra in front of him, and a she-ass and a bitch of ours were playing in front of him, but he paid no attention to that.” Abu Dawud transmitted it and Nasa’i has something similar.
