[Machine] I heard Abu Uthman say, "The book of Umar came to us while we were in Azerbaijan with Utbah bin Farqad. After that, fold your clothes, put on shoes, throw pebbles, cut your garments, and wear the clothing of your father Ismail. Beware of luxury and the attire of non-Arabs. Expose yourselves to the sun, as it is the Arab's bath. Be modest and composed, throw away unnecessary belongings, and isolate yourselves. The Prophet ﷺ forbade us from wearing silk, except for these two fingers, the index and middle fingers." He said, "We did not understand that he meant anything other than flags."

سَمِعْتُ أَبَا عُثْمَانَ يَقُولُ «أَتَانَا كِتَابُ عُمَرَ وَنَحْنُ بِأَذْرَبِيجَانَ مَعَ عُتْبَةَ بْنِ فَرْقَدٍ أَمَّا بَعْدُ فَاتَّزِرُوا وَارْتَدُوا وَانْتَعِلُوا وَارْمُوا بِالْخِفَافِ وَاقْطَعُوا السَّرَاوِيلَاتِ وَعَلَيْكُمْ بِلِبَاسِ أَبِيكُمْ إِسْمَاعِيلَ وَإِيَّاكُمْ وَالتَّنَعُّمَ وَزِيَّ الْعَجَمِ وَعَلَيْكُمْ بِالشَّمْسِ فَإِنَّهَا حَمَّامُ الْعَرَبِ وَاخْشَوْشِنُوا وَاخْلَوْلِقُوا وَارْمُوا الْأَغْرَاضَ وَانْزُوا نَزْوًا وَالنَّبِيُّ ﷺ نَهَانَا عَنِ الْحَرِيرِ إِلَّا هَكَذَا أُصْبُعَيْهِ وَالْوسْطَى وَالسَّبَّابَةِ» قَالَ فَمَا عَلِمْنَا أَنَّهُ يَعْنِي إِلَّا الْأَعْلَامَ
