Abu Hurairah reported the Prophet ﷺ as saying “Do not treat the backs of your beasts as pulpits, for Allaah has made them subject to you only to convey you to a town which you cannot reach without difficulty and He has appointed the earth (a floor to work) for you, so conduct your business on it.  

عَنِ النَّبِيِّ ﷺ قَالَ إِيَّاكُمْ أَنْ تَتَّخِذُوا ظُهُورَ دَوَابِّكُمْ مَنَابِرَ فَإِنَّ اللَّهَ إِنَّمَا سَخَّرَهَا لَكُمْ لِتُبَلِّغَكُمْ إِلَى بَلَدٍ لَمْ تَكُونُوا بَالِغِيهِ إِلاَّ بِشِقِّ الأَنْفُسِ وَجَعَلَ لَكُمُ الأَرْضَ فَعَلَيْهَا فَاقْضُوا حَاجَتَكُمْ
