Sahih al-Bukhari, Volume 7, Book 72, Hadith 793 (USC-MSA) ⓘ
Narrated Anas: The Prophet had big hands and feet, and I have not seen anybody like him, neither before nor after him, and his palms were soft.
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم ضَخْمَ الْيَدَيْنِ وَالْقَدَمَيْنِ حَسَنَ الْوَجْهِ، لَمْ أَرَ بَعْدَهُ وَلاَ قَبْلَهُ مِثْلَهُ، وَكَانَ بَسِطَ الْكَفَّيْنِ.
