"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
