Sa’id al-Jariri quoted Abu al-Tufail as saying:

I saw the Messenger of Allah(ﷺ). I asked: How did you see him? He said: He was white, good-looking, and when he walked, it looked as if he was descending to a low ground.

حَدَّثَنَا حُسَيْنُ بْنُ مُعَاذِ بْنِ خُلَيْفٍ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ الْجُرَيْرِيُّ، عَنْ أَبِي الطُّفَيْلِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم ‏.‏ قُلْتُ كَيْفَ رَأَيْتَهُ قَالَ كَانَ أَبْيَضَ مَلِيحًا إِذَا مَشَى كَأَنَّمَا يَهْوِي فِي صَبُوبٍ ‏.‏
