Hadith 5790
`Ali b. Abu Talib said: God's messenger was neither tall nor short, he had a large head and beard, the palms of his hands and his feet were calloused, he had a reddish tinge, he had large joints, the hair on his breast was long, and when he walked, he bent forward as though he were descending a slope. I have never seen anyone like him before or since. Tirmidhi transmitted it, saying this is a hasan sahih tradition.
عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَيْسَ بالطويل وَلَا بالقصير ضخم الرَّأْس واللحية شئن الْكَفَّيْنِ وَالْقَدَمَيْنِ مُشْرَبًا حُمْرَةً ضَخْمَ الْكَرَادِيسِ طَوِيلَ المَسْرُبَةِ إِذا مَشى تكفَّأ تكفُّأً كَأَنَّمَا يَنْحَطُّ مِنْ صَبَبٍ لَمْ أَرَ قَبْلَهُ وَلَا بَعْدَهُ مِثْلَهُ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ. رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
