The Messenger of Allah ﷺ came to us accompanied by Abbas when we were in open country belonging to us. He prayed in a desert with no sutrah 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. (Using translation from Abū Dāʾūd 718)
أَتَانَا رَسُولُ اللهِ ﷺ وَنَحْنُ فِي بَادِيَةٍ وَمَعَهُ عَبَّاسٌ فَصَلَّى فِي صَحْرَاءَ لَيْسَ بَيْنَ يَدَيْهِ سُتْرَةٌ وَحِمَارَةٌ لَنَا وَكُلَيْبَةٌ تَعْبَثَانِ بَيْنَ يَدَيْهِ فَمَا بَالَى ذَلِكَ
