Jami` at-Tirmidhi, Volume 6, Book 46, Hadith 3648 (DarusSalam) ⓘ

Narrated Abu Hurairah: "I have not seen anything more beautiful than the Messenger of Allah. It was as if the sun flowed upon his face. And I have not seen anyone quicker in his walking than the Messenger of Allah. It was as if the earth was made easy for him. We would be exerting ourselves while he would not be struggling."

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ لَهِيعَةَ، عَنْ أَبِي يُونُسَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ مَا رَأَيْتُ شَيْئًا أَحْسَنَ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم كَأَنَّ الشَّمْسَ تَجْرِي فِي وَجْهِهِ وَمَا رَأَيْتُ أَحَدًا أَسْرَعَ فِي مَشْيِهِ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم كَأَنَّمَا الأَرْضُ تُطْوَى لَهُ إِنَّا لَنُجْهِدُ أَنْفُسَنَا وَإِنَّهُ لَغَيْرُ مُكْتَرِثٍ ‏.‏ قَالَ هَذَا حَدِيثٌ غَرِيبٌ ‏.‏
