Hadith 120

llyas ibn Salama al-Akwa reported that his father said: "'Uthman ibn 'Affan used to wear a loincloth reaching the middle parts of his shins, and he said: 'In this manner was the loincloth of my Companion', meaning the Prophet (Allah bless him and give him peace).”

حَدَّثَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ اللهِ بْنُ الْمُبَارَكِ، عَنْ مُوسَى بْنِ عُبَيْدَةَ، عَنِ إِيَاسِ بْنِ سَلَمَةَ بْنِ الأَكْوَعِ، عَنْ أَبِيهِ، قَالَ‏:‏ كَانَ عُثْمَانُ بْنُ عَفَّانَ، يَأْتَزِرُ إِلَى أَنْصَافِ سَاقَيْهِ، وَقَالَ‏:‏ هَكَذَا كَانَتْ إِزْرَةُ صَاحِبِي، يَعْنِي النَّبِيَّ صلى الله عليه وسلم‏.‏
