"The Prophet dispatched me for something he needed. I came to him while he was performing Salat on his mount, heading east, he made the prostrations lower than the bowing."
بَعَثَنِي النَّبِيُّ ﷺ فِي حَاجَةٍ فَجِئْتُ وَهُوَ يُصَلِّي عَلَى رَاحِلَتِهِ نَحْوَ الْمَشْرِقِ وَالسُّجُودُ أَخْفَضُ مِنَ الرُّكُوعِ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ وَابْنِ عُمَرَ وَأَبِي سَعِيدٍ وَعَامِرِ بْنِ رَبِيعَةَ
The Messenger of Allah ﷺ sent me on some business, and when I came to him he was praying on (the back of) his riding beast (moving) towards the east and making the prostration lower than the bowing.
بَعَثَنِي رَسُولُ اللَّهِ ﷺ فِي حَاجَةٍ قَالَ فَجِئْتُ وَهُوَ يُصَلِّي عَلَى رَاحِلَتِهِ نَحْوَ الْمَشْرِقِ وَالسُّجُودُ أَخْفَضُ مِنَ الرُّكُوعِ
[Machine] The Prophet ﷺ sent me for a need, so I came to him while he was praying on his riding animal towards the east. The prostration is lower than the bowing, so I greeted him, but he did not respond to me. When he finished, he said, "I was praying."
بَعَثَنِي النَّبِيُّ ﷺ لِحَاجَةٍ فَجِئْتُ وَهُوَ يُصَلِّي عَلَى رَاحِلَتِهِ نَحْوَ الْمَشْرِقِ وَالسُّجُودُ أَخْفَضُ مِنَ الرُّكُوعِ فَسَلَّمْتُ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيَّ فَلَمَّا فَرَغَ قَالَ إِنِّي كُنْتُ أُصَلِّي
