Ash-Shama'il Al-Muhammadiyah 85
Abu Huraira said:
“The sandals of Allah’s Messenger (Allah bless him and give him peace) had two thongs, as did those of Abu Bakr and 'Umar (may Allah the Exalted be well pleased with them), and the first to tie a single knot was 'Uthman (may Allah be well pleased with him).”
حَدَّثَنَا مُحَمَّدُ بْنُ مَرْزُوقٍ أَبُو عَبْدِ اللهِ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ قَيْسٍ أَبُو مُعَاوِيَةَ، قَالَ‏:‏ حَدَّثَنَا هِشَامٌ، عَنْ مُحَمَّدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ‏:‏ كَانَ لِنَعْلِ رَسُولِ اللهِ صلى الله عليه وسلم قِبَالانِ وَأَبِي بَكْرٍ وَعُمَرَ، وَأَوَّلُ مَنْ عَقَدَ عَقْدًا وَاحِدًا عُثْمَانُ رضي الله عنه‏.‏‏.‏
