Musnad Ahmad 947
It was narrated that Nafi’ bin Jubair bin Mut`im said. `Ali (رضي الله عنه) was asked about how the Prophet (ﷺ) looked. He said:
He was not short and not tall, and he had a reddish colour and beautiful, slightly wavy hair. He had large joints and large hands, a large head and a long line of hair running from his chest to his navel. When he walked, he walked energetically as if he was walking downhill, I have never seen anyone like him (ﷺ) before or after.
حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنِي أَبُو الشَّعْثَاءِ، عَلِيُّ بْنُ الْحَسَنِ بْنِ سُلَيْمَانَ حَدَّثَنَا أَبُو خَالِدٍ الْأَحْمَرُ، سُلَيْمَانُ بْنُ حَيَّانَ عَنْ حَجَّاجٍ، عَنْ عُثْمَانَ، عَنْ أَبِي عَبْدِ اللَّهِ الْمَكِّيِّ، عَنْ نَافِعِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ، قَالَ سُئِلَ عَلِيٌّ رَضِيَ اللَّهُ عَنْهُ عَنْ صِفَةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ لَا قَصِيرٌ وَلَا طَوِيلٌ مُشْرَبًا لَوْنُهُ حُمْرَةً حَسَنَ الشَّعَرِ رَجِلَهُ ضَخْمَ الْكَرَادِيسِ شَثْنَ الْكَفَّيْنِ ضَخْمَ الْهَامَةِ طَوِيلَ الْمَسْرُبَةِ إِذَا مَشَى تَكَفَّأَ كَأَنَّمَا يَنْحَدِرُ مِنْ صَبَبٍ لَمْ أَرَ مِثْلَهُ قَبْلَهُ وَلَا بَعْدَهُ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ‏.‏
