Tirmidhi Book 49, Hadith 3637

حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيل، حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا الْمَسْعُودِيُّ، عَنْ عُثْمَانَ بْنِ مُسْلِمِ بْنِ هُرْمُزَ، عَنْ نَافِعِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ، عَنْ عَلِيٍّ، قَالَ:‏‏‏‏ لَمْ يَكُنْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالطَّوِيلِ وَلَا بِالْقَصِيرِ، ‏‏‏‏‏‏شَثْنَ الْكَفَّيْنِ وَالْقَدَمَيْنِ، ‏‏‏‏‏‏ضَخْمَ الرَّأْسِ ضَخْمَ الْكَرَادِيسِ، ‏‏‏‏‏‏طَوِيلَ الْمَسْرُبَةِ إِذَا مَشَى تَكَفَّأَ تَكَفُّؤًا كَأَنَّمَا انْحَطَّ مِنْ صَبَبٍ لَمْ أَرَ قَبْلَهُ وَلَا بَعْدَهُ مِثْلَهُ . قَالَ أَبُو عِيسَى:‏‏‏‏ هَذَا حَسَنٌ صَحِيحٌ.

Narrated 'Ali: The Prophet (ﷺ) was not tall nor was he short, his hands and feet were thick, his head was large, he was big-boned, he had a long Masrubah (the line of hair from the chest to the navel), and whenever he walked, he leaned forward as if he was going down a decline. I have not seen anyone before him nor after him that resembled him (ﷺ).
